为保障城市出风口的通畅,减少空气中污染物的聚集,北京市将对建筑物的高度和密度加以限制。据北京市规划委员会消息,北京旧城,海淀山后地区,延庆、怀柔、密云等新城及房山燕房地区的建筑高度将受到严格控制。北京市规划委员会联合北京市环保局和气象局研究发现,北京的大气污染主要来源于交通、燃煤、粉尘和沙尘污染,城市自身生态系统对大气自净功能较弱,环境承载能力相对不足。而且,北京的污染物排放在一定程度上受到扩散条件的影响,建筑
To ensure the smooth flow of urban air outlets and reduce the accumulation of pollutants in the air, Beijing will limit the height and density of buildings. According to the Beijing Municipal Planning Commission, the height of buildings in the old cities of Beijing, Haidian Behind, Yanqing, Huairou, Miyun, and Fangshan Yanfang will be strictly controlled. Beijing Municipal Planning Commission jointly with the Beijing Municipal Environmental Protection Bureau and the Bureau of Meteorology found that Beijing’s air pollution comes mainly from pollution of transportation, coal, dust and dust. The city’s own ecosystem has a weak self-purification function to the atmosphere and a relatively insufficient environmental carrying capacity. Moreover, the emission of pollutants in Beijing is affected to some extent by the diffusion conditions of buildings
