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.

拆墻透綠也能提高城市通風(fēng)散霾能力，經(jīng)濟(jì)成本也比較低，還能亮化城市、改善城市形象。因此建議，從國家層面倡導(dǎo)大中城市開展拆墻透綠工作，鼓勵拆墻透綠等亮化城市、改善城市通風(fēng)能力的行動。

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.

制定拆墻透綠等提高城市通風(fēng)散霾能力的鼓勵政策，將拆墻透綠列為生態(tài)宜居城市建設(shè)考量的一項內(nèi)容。還可選擇一些城市作為示范樣點(diǎn)，先行開展拆墻透綠，總結(jié)經(jīng)驗，形成可學(xué)可仿的樣板。

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.

同時，嚴(yán)格限制在建和待建小區(qū)四周完全被鋪面或墻體圍死，要留出足夠的透氣通道，用通透圍欄替代圍墻。待建城區(qū)在規(guī)劃建筑物布局時，要充分考慮當(dāng)?shù)刂饕獨(dú)饬黠L(fēng)向和風(fēng)力，為通風(fēng)散霾留出足夠的通道。

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.
