　　Xinhuanet feature: Medvedev officially succeeded Putin as president on May 7. The reporter recently interviewed Russians and found that most of them are optimistic and calm about the replacement of state leaders. They believe that the people’s life in the "Medvedev era" will continue to improve, and the new president will lead Russia to move forward along the "Putin line."

　　Inherit a rich political legacy

　　　　Vladimir konovalov, a 57-year-old worker at Moscow Electric Machinery Factory, is a supporter of United Russia. Konovalov said that Russia is entering the "Medvedev era". Medvedev will continue to carry out reforms and effectively develop the national economy after taking office, but all this must be attributed to the valuable political legacy left by Putin. It is Putin who has defended national unity, achieved national unity, reversed the domestic economic downturn and won the trust of the people, all of which are prerequisites for the further development of the country.

　　　　Konovalov said that during Putin’s years in office, the income of ordinary people, especially low-income people, has been greatly increased, and everyone is very grateful for this. It is this credit that makes Putin a public opinion leader with unprecedented support rate in Russia. Although inflation has not been effectively controlled during his term of office, people are still full of confidence in the future because the income level of residents has been improving.

　　　　When Putin came to power, the situation he faced was much more complicated. His urgent task at that time was to end sharp ethnic conflicts, curb the deteriorating momentum of people’s livelihood, eliminate the constant attacks by terrorists in the North Caucasus, avoid the disintegration of the army, and the distrust of the Russian people in the authorities after frequent political fluctuations. These problems have been effectively solved during Putin’s tenure. From a certain point of view, Medvedev is luckier. He came to power in a relatively stable period. Although there are internal and external troubles, it is not so sharp.

　　Internal affairs: not simply inherited

　　　　Sergei Kutakhov, an expert at the St. Petersburg Institute of Political Studies, believes that Russia’s transition from the "Putin era" to the "Medvedev era" has been quite smooth.

　　　　He believes that Medvedev will undoubtedly continue to implement various development policies set by Putin. He said that in the past, when the new president took office, there was always a sharp difference in line with the former president, but now the situation is completely different, which is a new phenomenon in Russian political life. This shows that the political high-level officials have reached an agreement on the political line.

　　　　Economically, Russia is currently an influential energy power and the seventh largest economy in the world. Obviously, Medvedev will also make good use of the opportunities he faces to actively develop the economy and push Russia’s economic ranking forward. In addition to energy means, Medvedev is trying to promote new liberal values in Russia, including respecting private property and intellectual property rights, supporting the development of agriculture, animal husbandry and small and medium-sized enterprises, etc. Some of these areas will become new locomotives of Russian economic development.

　　　　If Putin mainly relies on petrodollars to achieve economic development breakthrough, then Medvedev will face a more complicated task-to improve the country’s economic strength by cultivating and developing innovative economy. In fact, this task also occupies a place in Putin’s policy, but it will be a typical feature of economic policy in the "Medvedev era" to a greater extent. In this respect, Medvedev’s policy is not a simple inheritance compared with Putin’s period, but an innovative move.

　　Diplomacy: Meeting Western Challenges

　　　　With the increasing prestige and competitiveness of Russia in the world, it has also encountered greater pressure and containment from the United States and other western countries. This power to contain Russia will continue to increase, especially in the early days of Medvedev’s presidency. Western political opponents will inevitably try to test Medvedev’s strength with this pressure, which will undoubtedly push Russia to seek new cooperation with its strategic partners-CIS countries, China, India and other developing countries.

　　　　Konstantin Galipaud, a reporter from Voice of Russia Radio, said that Medvedev, as president-elect, made the first contact with the leaders of the United States, Germany, Japan, Egypt and other countries. Judging from his performance, he would have no difficulty in pursuing his own foreign policy. Medvedev served as the chief of the president’s office, the first deputy prime minister and a member of the security Council. He was one of the co-makers of Russian foreign policy. In addition, he also served as the main person in charge of some foreign affairs. For example, as the chairman of the Russian Organizing Committee, he was responsible for the organization of the "Year of the Country" between China and Russia.

　　　　He believes that Putin’s outstanding performance in the diplomatic field is enough for Medvedev to refer to, but according to various circumstances, Medvedev is definitely not a novice in diplomatic occasions. However, the west is not willing to admit that there is a new outstanding leader in Russia quickly, and begins to do its best to widen the gap between Putin and Medvedev’s image and slander and slander Medvedev, which will become a new challenge for Medvedev personally.

After two seasons of "Yellow River Articles" showing the great changes in people’s lives along the "Yellow River Ecological Economic Belt", Running Bar in 2022 ushered in "Common Prosperity". As one of the key radio and television programs of the State Administration of Radio and Television in 2022, Zhejiang Satellite TV’s "Run for Common Prosperity" was launched on November 4, which consolidated and expanded the achievements of poverty alleviation and advanced towards common prosperity in the country, presented the development of contemporary new countryside to the audience, and introduced the staged achievements of common prosperity.

You Minchao, the general director of this season, said, "The program group combines the main theme content with the creation of variety shows, hoping to present the achievements of beautiful countryside’s construction in an entertaining form and expose the transcripts of new rural construction."

Witness the "Common Wealth Map" of Rural Revitalization

As a series of "Run" and "Special Season", You Minchao regards "Common Prosperity" as a continuation and an upgrade of the theme creation of this series.

You minchao

Since 2020, Zhejiang Satellite TV’s Running Bar has started the shooting and broadcasting form of "regular season" in the first half of the year and "special season" in the second half of the year. You Minchao introduced that the theme of the "special season" will be constantly adjusted according to the national policy. In the first two seasons, the "Yellow River Chapter" relied on the "Yellow River Ecological Economic Belt" and entered the coastal cities to enjoy a new look; "Common Prosperity" focuses on exploring the characteristics of new countryside in different regions, with beautiful countryside and common prosperity as the main theme.

"Compared with’ Yellow River’ which shows the local differential transformation from poverty to wealth, this year’s program is more like showing the transcripts of top students to the audience, so that everyone can see what common prosperity is and how to promote it, and provide a model and a reference for everyone." You Minchao said that at the beginning of the preparation, the program group conducted in-depth discussions around "how to show common prosperity". First, it solved a series of problems such as "where to shoot and what to shoot", and finally decided the shooting direction: demonstration sites and model sites under this theme.

This season, we will focus on the advanced figures who promote the cause of common prosperity in rural areas, introduce the pioneering experience of high-quality development, and pursue the struggle footprints of new farmers in the new era and witness the "common prosperity map" of rural revitalization by showing the modern countryside, agriculture and farmers in Jiande, Chun’ an, Zhejiang and Sanming, Fujian, as well as the characteristics of local new rural construction.

In the broadcast program, the audience followed the program group to experience the unmanned agricultural planting industry in Xin ‘anjiang, the smart medical system in Zhijiang Village and the common prosperity of Qiandao Lake, and witnessed the rural appearance of the new era under different conditions. The first program introduces unmanned agriculture, and many viewers feel the rapid development of modern agriculture through barrage and imagine the beautiful vision of future agriculture; The second phase of Meicheng Ancient Town and the third phase of Qiandao Lake scenery attracted the audience to call it "on the punch list".

Setting up tasks skillfully to show the characteristics of new countryside

You Minchao told the reporter of Variety Daily that the location selection of "Common Prosperity" is actually more difficult than "Yellow River". "Yellow River" has a geographical frame, with its own elements of the Yellow River. The biggest difficulty in shooting is to dig deep into the content of the selected place; The location selection of "Common Prosperity" is national, and the main creative team needs to go through a lot of screening in the early stage. "The program group is in dozens of provinces across the country, and each province chooses one or two counties and cities; Then the director integrated the analysis materials, screened the characteristics and finally determined the shooting location-the whole process lasted for several months. "

However, this "theme first" creative method also reduces the burden for subsequent creation: in "Common Prosperity", the location of shooting and the determination of characteristic content are almost synchronous, and the program group pays more attention to how to present local characteristics in an entertaining way through tasks and shots.

For example, the theme of "new farmer" in the first program and "rural tourism" in the second program are the core elements of the rapid development of the local area. Based on this, the program group designed supporting content, combining the form of "Heroes of the Marsh Card" with the image of "new farmer" and combining the travel bill with rural tourism, so that the task theme and the content theme are related and interactive, and the educational and entertaining program effect is realized.

Combine the advantages of variety show to tell the story of China.

After three seasons of "special season" creation, "Running Bar" has accumulated rich experience in how variety shows are presented in an entertaining way around the main theme. For example, in the first season, "Yellow River" tells the story of Minning Town, adopting the form of guest substitution experience, and presenting the development of Minning Town after its relocation through the stories of people at different time nodes. The development story of Shaxian County in Fujian Province in "Common Prosperity" tries to tell the process of Shaxian snacks going out of Fujian and going to the whole country from a small village through game packaging and "upgrading through customs".

You Minchao said that it is difficult to interpret the connotation behind the construction and development of beautiful countryside in depth and detail through a program. Therefore, "Common Prosperity" selects key elements and important development nodes, and tries to "explain a core content thoroughly and clearly through various forms" on the premise of ensuring professionalism, which is also one of the program effects pursued this season.

In "Common Prosperity", the creative team used the forms of treasure hunting, competitive confrontation and professional experience to present the characteristic agriculture, scenic spot development, career and business model exploration in different shooting locations, attracted the audience with dramatic conflicts, led the audience to appreciate the brand-new and vigorous rural landscape, and described the advantages of the "model" in the program and the process of its becoming a "model".

In You Minchao’s view, the development process of beautiful countryside is presented through task deduction. "The introduction of the main theme content can no longer be a boring exposition." The attribute of the outdoor reality show "Run" corresponds to the great rivers and mountains of the motherland-going out of the studio and letting the audience observe the changes taking place in different fields of the country from multiple angles-which is the advantage of this kind of program in creating the main theme. He believes that combining the advantages of variety shows, through the setting of task links and the dismantling of the process of change, the main theme content can be truly publicized into the brain and the heart.

As early as a year ago, Wang Ge wanted to change a family car because of personal needs. He took the right one.Dongfeng NissanWith the appreciation and expectation of the brand, I went to the local 4S shop and drove a car home with great joy. I chose 23 models of 1.6 cut and enjoyed it, landing 113,800. At that time, he was full of love for its fashionable appearance and comfortable seats. Now I’ve bought it for more than a year, and I’ve driven a 15,632-kilometer Dongfeng Nissan Sylphy to share the car experience with you.

Through my own car experience during this period, I summed up several advantages and disadvantages of Nissan Sylphy, and made a reference for the owners who want to buy this car. Let me talk about what I found.

Let’s talk about shortcomings first:

1. Poor power:I’ve been driving this Sylphy car for more than a year. The 1.6L engine is really a bit meaty. If you run at a high speed, it’s a little hard to overtake after 120 km/h. At this time, stepping on the accelerator will be a dry roar. After all, the 1.6L small-displacement engine doesn’t have a turbine, and the rear section is a little overwhelmed. This is understandable, but as a household scooter at ordinary times, the power is still enough.

2. Loud noise: Sylphy’s sound insulation Although Nissan has made efforts, netizens have not commented well, and there is basically no sound insulation. Just like the heavy rain, the noise in the car is still quite loud, but the sound that falls on the car is still quite obvious. Moreover, when driving at high speed, you can also hear the tire noise, which may affect the driving experience.

3. Interior materials are average: most of Sylphy’s interior materials are made of hard plastic, which may affect the interior texture of the car. Moreover, in today’s fierce competition of new energy vehicles, the interior of Nissan Sylphy has hardly changed. Compared with the new domestic forces, it is really like antiques. For car owners who pay attention to interior quality, this may be a consideration.

Let’s talk about the advantages:

1. Good-looking appearance: The choice of Sylphy has a great part to do with its appearance. The appearance design is fashionable and atmospheric, especially the shape of the car body. The lines are very smooth, in line with modern aesthetics, and the size of the car body is relatively long, which can leave a deep impression on people.

2. Good comfort: Sylphy is quite comfortable to ride in the car. Sylphy adopts Nissan classic design and zero-gravity seats. At that time, the family sat in it for a test drive, which felt like a big sofa. Sylphy’s suspension system was also quite excellent. It can effectively prevent bumps when passing rough roads, and it is soft to sit on, which can provide us with a quiet and stable driving environment.

3. High fuel and maintenance economy: Sylphy’s 1.6L naturally aspirated engine, combined with CVT continuously variable transmission, has low fuel consumption for daily household use, which can save our province a little fuel cost, and the comprehensive fuel consumption is about 7-8L/100km. Moreover, the maintenance of Sylphy is also relatively cheap: the daily maintenance and simple maintenance of Sylphy are generally done for a few hundred dollars, and the after-sales service network is relatively perfect.

The above is my real car experience of driving less than 20,000 kilometers for half a year, and summarizes these shortcomings for the reference of riders. There is no perfect car, just buy one that suits you. I hope it can help you!

What shortcomings or bad places do you think are there to communicate in the comment area ~

new styleMercedes-benz a-class AMGHere comes the series! The hatchback is imported and the sedan is made in China, and the price is 405,100 yuan and 409,400 yuan respectively. Young people’s dream of high performance, this time really smells good!

The two models listed this time are AMG A 35 4MATIC (hatchback version) and AMG A 35 L 4MATIC (sedan version).

Among them, the hatchback version is directly imported from overseas, and the sedan version is a domestic masterpiece of Beijing Benz.

Not only has the appearance and interior been upgraded in an all-round way, but the power system has also added 48V light mixing technology, which makes the performance more outstanding!

The agility of the hatchback and the steadiness of the sedan, which one is more suitable for you?

Let’s find out.

oneAppearance: straight waterfall grille+brand-new lamp group, the lamp factory really did not disappoint!

Mercedes-Benz’s design has never been disappointing, and the new A-class AMG series has carried out the reputation of "lighting factory" to the end.

Both models have been replacedAMG family-style straight waterfall air intake grilleWith the brand-new LED light group, the visual impact is directly full.

Coupled with the AMG nameplate and the new design, the sporty atmosphere of the whole car is on the top!

The split taillight style at the rear of the car has also been redesigned, which is highly recognizable after lighting.

The exhaust layout of bilateral double outlets tells everyone: although I have a high face value, I am not a "grocery cart".

Hub aspectThe new AMG A 35 L 4MATIC (domestic sedan version) comes standard with 19-inch AMG double five-spoke aluminum alloy wheels, with gray brake calipers and perforated brake discs, which is full of performance.

In contrast, the dynamic temperament of the hatchback version is more prominent, and the import identity itself has a little "face-to-face", so it is no problem to walk out and shake your head.

2Interior: dual screen +Nappa steering wheel, luxury and sense of technology Qi Fei!

The interior of Mercedes-Benz A-class AMG has raised the sense of luxury and technology to a higher level this time.

Double screen designIt is still the highlight of the audience. The LCD dashboard and the central control screen are integrated, equipped with the second-generation MBUX car system, and the interactive experience is more silky. Navigation, entertainment, vehicle settings, and even voice control are all in the air.

The steering wheel has been changedThe latest AMG Nappa leather sports steering wheel, feel great!

The steering wheel is also integrated with AMG control components, and the driving mode switching and suspension adjustment can be done with one button, which is both scientific and convenient to operate.

Coupled with AMG-style sports seats, you can feel the fighting atmosphere when you sit in.

The interior materials have also maintained the consistent high standard of Mercedes-Benz, and the carbon fiber decorative board and the air outlet of the barrel air conditioner continue to be online, and the overall texture has not been picked. The rear space of the sedan version performs better, and it is completely fine for daily use.

threePower: 2.0T+48V light mixing, the track start mode is directly full!

When it comes to AMG, motivation is definitely an unavoidable topic.

This new A-class AMG series is fully equipped.2.0T four-cylinder turbocharged engineThe maximum power is 306 HP and the peak torque is 400 Nm.

To match this,8-speed wet dual clutch gearbox (AMG SPEEDSHIFT DCT)The speed of shifting gears is so fast that people doubt life.

48V light mixing systemIt is also a bright spot. The light hybrid motor provides an additional 14 horsepower and 150 Nm of torque when accelerating, which makes the dynamic response faster and improves fuel economy.

The acceleration time from 0 to 100 km/h is 4.9 seconds (hatchback version) and 5.1 seconds (sedan version), and the maximum speed is electronically limited at 250 km/h.

Race-Start mode is to directly satisfy your control desire, and come to a sprint with bursting performance anytime and anywhere.

fourDaily driving experience: comfort and passion coexist, and safety is also full!

Don’t think that AMG only has performance. The new A-class AMG series is also very good at comfort and safety.

Driving modeSupport a variety of choices, including comfort, sports, sports+,skiing, personalization, etc., whether commuting or going wild on weekends, you can find a driving experience that suits you. The blessing of the four-wheel drive system further improves the stability of the vehicle in corners and has more confidence in daily driving.

The security configuration is also unambiguous, includingActive braking assistance, lane keeping assistance, blind spot monitoring, adaptive cruise, traffic sign recognition.Active and passive safety systems are available.

L2-level intelligent driver assistance system can also achieve partial automatic driving on high-speed and urban roads, freeing hands and making the journey easier.

fiveComparison at the same level: Lectra 03+ TCR Cyan, Honda Civic Type R, who can play better?

In the price range of 400 thousand, there are not many high-performance compact cars that can be taken. In addition to Mercedes-Benz A-class AMG, Lectra 03+TCRCYAN (RMB420,300) and Honda Civic Type R (RMB420,000) are also the hearts of "performance players".

Lingke 03+ TCR CyanThe guide price of AMG A 35 is slightly higher than that of AMG A 35, and the front drive layout and 2.0T engine, although the power parameters and acceleration performance are also good, the sense of luxury and brand influence is still a little worse than that of Mercedes-Benz.

If you are more interested in personalized appearance and performance adjustment, you can consider lectra.

Honda civic Type RIt can be said that it is the top flow in the "driving toy", and the 2.0T engine +6MT manual gearbox directly fills the control fun.

But after all, Type R is a pure performance car, and its daily comfort and luxury configuration are not as good as Mercedes-Benz A-class AMG.

If you are a manipulation fanatic, the Civic Type R is definitely worth a try.

In contrast, the new Mercedes-Benz A-class AMG series is more like an all-round player. It not only has strong power output and rich driving modes, but also has luxurious interior and rich technology configuration, which is correct for daily commuting and weekend hurricane.

6.400 thousand’s high-performance luxury car, it smells good this time!

The strength of the new Mercedes-Benz A-class AMG series can not be underestimated:Fashionable appearance, luxurious interior, strong power and rich configuration.Coupled with the blessing of the Mercedes-Benz brand, it is simply the perfect answer for young people to pursue high-performance compact cars.

The imported version of the hatchback is more agile, and the domestic version of the sedan is more practical. How to choose it depends on your needs.

　　China Meteorological News correspondent Dong Yongchun Wang Ting

　　Recently, the "Guangdong Province Air Pollution Prevention and Control Strengthening Measures and Division of Labor Plan" (hereinafter referred to as the "Strengthening Plan") issued by the General Office of the Guangdong Provincial Government proposed that "all localities should fully consider the long-term impact of climate change when planning, designing and approving urban infrastructure construction and renovation projects, and prohibit the construction of new high-rise buildings on urban ventilation corridors." This is also the first time that urban ventilation corridors have been written into Guangdong’s environmental protection policy.

　　In recent years, Beijing, Hangzhou, Wuhan, Xi ‘an, Chengdu, Guangzhou, Huizhou and other places have brought ventilation corridors into the vision of planning and decision-making. Among them, Guangzhou was listed as the second batch of national urban design pilot cities by the Ministry of Housing and Urban-Rural Development this year. The overall urban design of Guangzhou, which is being compiled, also requires further establishment of a more detailed ventilation corridor scheme.

　　Why do ventilation corridors attract the attention of more and more cities? How should it be planned and constructed, and will the areas along the line face large-scale demolition and construction? With these questions, the author interviewed Wang Chunlin, deputy director of Guangzhou Climate Center and a senior engineer at the research level.

　　Why build it?

　　-It can reduce air pollution and alleviate the urban heat island effect.

　　As early as two or three years ago, urban ventilation corridor has been included in the research field of Guangdong meteorological department. According to Wang Chunlin, the leader of the research team, the urban ventilation corridor is a passage for introducing fresh cold and humid air to the urban area with the purpose of improving the air mobility of the city, alleviating the heat island effect and improving human comfort. Generally speaking, the "ventilation corridor" is just like the "urban air duct", similar to a long and narrow ventilation duct, which can make the urban wind "pass through the hall".

　　"Our ventilation corridor planning is mainly based on the Technical Guide for Urban Ventilation Corridor Planning issued by China Meteorological Bureau at the end of 2015." Wang Chunlin said that many developed countries and regions have already started in this respect. Munich, Germany began the practice of introducing ventilation corridors into urban planning in the 1970s. Tokyo, Japan has long established a five-level ventilation corridor system combining mountains, valleys, sea, land and parks.

　　In 2006, the Hong Kong Planning Standards and Guidelines set out the definition and function of urban ventilation corridors (air ducts) in urban planning for the first time: ventilation corridors should be connected by large open areas, such as main roads, connected open spaces, beautification zones, non-construction sites, construction line backward zones and low-rise buildings. Ventilation corridors should extend in the direction of prevailing winds, and if feasible, other natural gas flows, including ocean, land and valley winds, should be maintained or guided to blow to urban areas.

　　Wang Chunlin believes that ventilation corridors have many advantages. "First, they can effectively alleviate the various impacts caused by urban heat island effect; second, they can help urban air flow and pollution diffusion; and third, they can greatly improve human comfort in terms of temperature and urban air quality."

　　Take Beijing as an example. In 2012, when the heat island area of six districts in the city center was serious, it accounted for 77% of the total area. In recent years, the trend of urban wind speed decreasing is also obvious. In this regard, He Yong, deputy director of the Planning Research Office of Beijing Urban Planning and Design Institute, said that the ventilation corridor is not to "create wind", but to make the cold air in the suburbs flow to the urban area more smoothly and "change" the hot air in the urban area, thus effectively reducing the urban temperature.

　　How to lay out?

　　-big data analysis of wind environment and planning according to local conditions

　　For cities with different geographical conditions, how to set the direction and route of ventilation corridors?

　　At present, the team led by Wang Chunlin is studying and experimenting to analyze the urban wind environment through huge data analysis and computer simulation experiments, which is an important basis for planning urban ventilation corridors. He introduced that at present, the analysis of urban wind environment mainly adopts the Mesoscale Meteorological Model (WRF), which is a new generation of mesoscale forecasting model and assimilation system jointly developed by American meteorological circles. The land surface process model in WRF is coupled with the Urban Canopy Model (UCM). By adjusting the regional urban parameters such as urban reflectivity and roughness, it has a good simulation ability for urban heat storage effect, flow field and precipitation distribution.

　　"To analyze the wind environment, we must first master a large number of urban underlying surface data and wind observation data." Regarding the design principle of urban ventilation corridor, Wang Chunlin said that the data of urban underlying surface include the distribution, height and geometric structure of buildings, as well as the distribution of terrain height, green space and water bodies. Wind observation data include wind force, wind direction and other elements. Taking Guangzhou as an example, the available wind observation data include the data of five national weather stations in Guangzhou in recent 30 years and about 300 regional weather stations in recent 10 years.

　　"Secondly, the fine-grid meteorological dynamic model is an important tool to carry out urban wind environment analysis and ventilation corridor planning effect evaluation." Wang Chunlin said that Guangzhou Meteorological Department has a large number of historical data and 400 trillion supercomputers per second, which can make statistical analysis on the output results of massive models and quantitatively compare the ecological benefits of different ventilation corridor planning schemes.

　　In the planning process, adapting to local conditions is an important principle. On the one hand, the existing ecological cold sources such as green space, parks, forests, rivers and lakes should be included in the wind gallery, which can better protect the ecological cold sources and make them play the role of purifying the air and reducing the urban heat island effect. On the other hand, the existing urban pattern should be fully respected, and the planning of wind corridors should try to avoid the existing large-scale buildings and avoid a large number of demolition.

　　"Just like urban roads have roads and paths, ventilation corridors are divided into first-class corridors and second-class corridors." Wang Chunlin said that the first-class corridor is equivalent to the main road and is the main ventilation corridor; The second-level corridor should be built along the area with great ventilation potential, and try to make up for the "broken" corridor area that the first-level corridor cannot guarantee.

　　At present, there are five or more main ventilation corridors in Beijing, Hangzhou, Chengdu and other cities, and there may be more secondary corridors.

　　On the principle of division of labor and design, the design of the first-class ventilation corridor should be as parallel or nearly parallel as possible to the dominant wind direction of the city, and make full use of the ecological cold sources such as green space, mountains and rivers with large area and good ecological environment. The setting of the secondary corridor should play the role of assisting and extending the ventilation efficiency of the primary ventilation corridor, and communicating and connecting the local ecological cold source and the areas with poor wind environment. With the help of urban trunk roads, squares, water systems and other open spaces, the final "wind corridor network" should be formed. The setting of the width, length, direction and land use control of the wind corridor should be combined with the refined wind and heat distribution characteristics and realistic construction conditions in the urban area.

　　What are the design principles?

　　-determine the direction of the wind corridor according to the prevailing wind direction in the city.

　　During the implementation of urban ventilation corridor planning, the stipulation that "no new high-rise buildings are built on urban ventilation corridors" mentioned in Guangdong’s "Strengthening Plan" has attracted much attention.

　　Does this mean that the existing buildings will be demolished and built? Wang Chunlin believes that the existing high-rise buildings should not be demolished artificially, but should be demolished by natural elimination after reaching the service life, so as not to waste resources.

　　It is forbidden to build new high-rise buildings on urban ventilation corridors for two reasons: first, high-rise buildings will increase the roughness of urban underlying surface and reduce the air circulation efficiency of air corridors, which is the bottleneck area of air flow. Second, the high-rise building on the wind gallery has a large windward wind speed, which has many disadvantages: a large area of quiet wind zone is formed at the back of the high-rise building, which will be extremely stuffy in summer and affect comfort; If there are pollutants in the back of it, it will cause air pollution in the near-surface layer and affect human health.

　　"Even if some buildings are very tall, whether they will have a great impact on the wind gallery requires specific analysis." Wang Chunlin said. It is assumed that the new central axis of Guangzhou, which extends from Tianhe North Road to flower city square, is also set as a ventilation corridor, and the towering small waist (also known as Guang Zhouta) is just in the middle below the central axis. However, due to the slender structure of the small waist building and the hollow design, it will not cause great obstruction to the wind corridor.

　　The prevailing wind direction in the city is the decisive factor affecting the direction of the wind corridor. Wang Chunlin said that taking many cities in the Pearl River Delta, such as Guangzhou, for example, the southeast wind prevails in summer and the northerly wind prevails in winter, and the north-south wind corridor is conducive to utilizing the ecological cold source in Conghua and other places in the north and the ocean cold source in the south.

　　At present, the Master Urban Design of Guangzhou, which is being compiled in Guangzhou, also clearly requires that the main corridors where the dominant wind direction enters the city should be determined, and the strategy of "making wind, gathering wind and ventilating" should be put forward to establish the urban wind corridors, water corridors, green corridors and visual corridors in Guangzhou.

　　How to implement the plan?

　　-there is still a lack of unified standards, and all localities are exploring.

　　When the Eight Immortals crossed the sea, they all showed their magical powers. In fact, at present, there is no uniform standard for urban ventilation corridors in mainland China, and all localities are still groping for it in practice.

　　Wang Chunlin revealed that Guangzhou was listed as the second batch of urban design pilot cities this year. In this year’s overall urban design of Guangzhou, the planning and design department initially planned and designed the ventilation corridor system of Guangzhou based on the numerical simulation of Guangzhou’s wind environment.

　　However, many cities that are more advanced in the research and planning of ventilation corridors also face some confusion in practice. For example, in many ventilation corridors planned and built in Beijing, there are still many high-rise and dense building communities, which will become the bottleneck area of air flow.

　　Wang Chunlin believes that the planning and improvement of urban ventilation corridors need to be fully discussed and communicated with urban planning departments to jointly promote the planning and implementation of ventilation corridors.

　　In fact, in addition to directly planning urban ventilation corridors, many places have also taken some measures to improve urban microclimate. For example, Shenzhen will treat the first floor of real estate as an overhead floor into the overall urban planning, and rationally arrange the layout of urban buildings; Thirty pilot cities, including Xiamen, Chongqing and Nanning, have accelerated the construction of "sponge cities".

　　Wang Chunlin revealed that the changes of local ventilation volume and heat island intensity before and after ventilation corridor planning can be accomplished by means of numerical simulation, field observation or wind tunnel test. Among them, the fine simulation of local wind environment can be carried out by computational fluid dynamics (CFD). He introduced that CFD is a combination of modern fluid mechanics, numerical mathematics and computer science. Using electronic computer as a tool, it applies various discrete mathematical methods to conduct numerical experiments, computer simulations and analytical studies on various problems of fluid mechanics in order to solve various practical problems. However, due to the huge demand for computing resources, CFD technology is usually applied to the simulation and analysis of wind field in residential areas, and a wider range of applications can be tried in the planning of urban ventilation corridors in the future.

　　Link: Controversy about Ventilation Corridor

　　There is a classic line in the movie "Be there or be square": Blast the Himalayas into a 50-kilometer-wide hole, let the warm and humid air from the Indian Ocean blow into the Qinghai-Tibet Plateau through Nepal, completely change the harsh ecological environment there, take off the backward hat there, and turn the Qinghai-Tibet Plateau into a beautiful and rich land of fish and rice. This line is also used to ridicule the ventilation corridor. Indeed, a new engineering design is still in the stage of scientific demonstration, which will cause a lot of controversy.

　　One of the focuses of controversy is whether the smog can be blown away. Opponents believe that the main reason for the smog in winter is that the cold air is weak, and the warm and humid air from the south goes north, and after the stalemate, it forms static weather. If you want to disperse the smog through the ventilation corridor, you must have wind first, but there is no wind in calm weather. Supporters believe that the existing research proves that the formation of ventilation corridor network in the central city is effective in improving the microclimate and has a certain auxiliary role in promoting the diffusion of pollutants.

　　Another focus of controversy is whether successful experiences can be replicated. According to reports, there is a burning wind every year in Munich, Germany, and five urban ventilation corridors are planned and built locally to let the burning wind pass through the city and take out the dirty air in the city. The effect is very good. However, some opponents believe that the wind burning in Munich is caused by the geographical factors on the northern slope of the Alps. Unlike the climate background of many cities, it is still unknown how much the ventilation corridor can play in other cities.

　　There are still some controversies surrounding the practical difficulties in construction. Some people think that urban construction is basically taking shape, and the landing of ventilation corridors in the future depends on urban planning, which is difficult to achieve overnight. Others question whether smog and heat waves will affect the surrounding areas if they are successfully dispersed by ventilation corridors. Supporters said, first, there is no need to "make a big move" on urban construction, just make a slight adjustment; Second, the pollutants carried away by air flow will not only spread to the open areas around the city, but also spread to the sky, and it is a process of gradual dilution, which will not affect the surrounding areas.(bian Ji)
