In many large and medium-sized cities, the population is overloaded, and the scale exceeds the self purification capacity of the environment. In urban planning, the main ventilation Road is not left enough in the layout of tall buildings, and the high wall barrier in a single residential area is private and airtight, which greatly hinders the dissipation of haze in large and medium-sized cities.

拆墙透绿也能提高城市通风散霾能力，经济成本也比较低，还能亮化城市、改善城市形象。因此建议，从国家层面倡导大中城市开展拆墙透绿工作，鼓励拆墙透绿等亮化城市、改善城市通风能力的行动。

It can also improve the ability of Urban Ventilation and haze dispersion, reduce the economic cost, brighten the city and improve the city image. Therefore, it is suggested that large and medium-sized cities should be encouraged to carry out the work of removing walls to make the city green, and other actions should be encouraged to brighten the city and improve the ventilation capacity of the city.

制定拆墙透绿等提高城市通风散霾能力的鼓励政策，将拆墙透绿列为生态宜居城市建设考量的一项内容。还可选择一些城市作为示范样点，先行开展拆墙透绿，总结经验，形成可学可仿的样板。

We should formulate incentive policies to improve the ability of Urban Ventilation and haze dispersion, such as breaking down walls and making them transparent, and list them as an important part of the construction of ecological and livable cities. Some cities can also be selected as demonstration sites to carry out wall demolition and greening first, and sum up experience to form models that can be learned and imitated.

同时，严格限制在建和待建小区四周完全被铺面或墙体围死，要留出足够的透气通道，用通透围栏替代围墙。待建城区在规划建筑物布局时，要充分考虑当地主要气流风向和风力，为通风散霾留出足够的通道。

At the same time, it is strictly limited that the area under construction or to be built is completely surrounded by pavement or wall. Sufficient ventilation channels should be reserved and permeable fences should be used instead of walls. When planning the layout of buildings in the urban area to be built, the local main airflow direction and wind force should be fully considered to leave enough channels for ventilation and haze dispersion.
