摘　　要：采用MM5/CALMET耦合模型,以理想环境容量A值法计算高分辨率的区域气象特征和环境容量分布,并将理想环境容量与足迹分析法相结合,提出基于高精度大气容量的烟云承载能力,分析不同区域内排放的大气污染烟云自净和扩散所需要空间,解决大气污染物总量控制如何与区域环境容量相结合的关系。最后以乌鲁木齐经济圈为例,计算得出乌鲁木齐市污染排放超载,但由于借用周边空间的自净能力,因此其SO2环境质量未超标。烟云足迹分析法有利于分析城市群内各城市的大气环境承载力和环境质量间的关系,为区域排污权交易提供技术基础。This paper used MM5 / CALPUFF modeling calculation of high spatial resolution of meteorological data and atmospheric environmental capacity of different cities. Base on the footprint method and ideal environment capacity, research discussesed pollution plume bearing capacity and bearing area. Taking Urumqi economic circle for example, the SO2 environment capacity of Urumqi had overloaded. Through the use of the surrounding city environmental capacity, Urumqi air quality coital meet the standard. The method of plume footprint has an advantage to the analysis of atmospheric environmental capacity of each city in the urban agglomeration, which can provide technology for regional emissions trading.
