Beijing considers 'wind corridors' to disperse smog   

北京研究“借風”吹散霧霾 把郊外的風引進城區

針對霧霾，北京又有新動作。目前，國家和北京的氣象部門正在研究北京的城市風道，正在修訂的北京城市總體規劃中將有專門章節闡述城市通道內容，預計相關研究結果將于今年年底發布。[查看全文]

(ECNS) – Beijing is discussing the construction of wind corridors through the city to deal with air pollution, the Beijing News reports.

A feasibility study of the project is underway, said Liu Chunlan, a research center leader at the Beijing Municipal Research Institute of Environment Protection. Issues on where to build the corridors and how to maintain them will be discussed, he said.

Liu added that control of building heights and densities along the direction of Beijing's prevailing winds can help disperse pollution and hot air.

Several big cities in China including Shanghai, Hangzhou, Wuhan and Nanjing have started to build ventilated corridors to bring in wind from suburbs to purify air and cool inner cities.

But Yang Baojun, chief urban planner at the China Academy of Urban Planning and Design, said ventilated corridors may be of very limited effectiveness in Beijing, as its urban planning was designed to resist cold and wind.

Concentrations of PM2.5 in Beijing reached 89.5 micrograms per cubic meter in 2013. The city has set a goal to bring down the concentration to 60 micrograms per cubic meter by 2017.
