摘　　要：为了在现有大气污染源排放清单建设工作中突出重点,进行有效的调研分析,需判断出区域大气的主要污染源和污染物,因此制定了区域大气污染物和污染源重要性排序的一般原则和计算方法。从现有国内研究中选取北京市、天津市、上海市、杭州市、广东省以及珠三角共6个有NO_x、SO_2、PM_(2.5)、PM_(10)、NH_3、VOCs、CO排放量研究结果的地区进行综合对比分析,根据等标污染负荷比法和狄克松检验法得出区域污染源和污染物重要性排序结果。根据通用方法,以扬州市为例,得出扬州市大气污染源重要性排序结果依次为:工业源、生活源、农业源、移动源和其他源,主要污染源为工业源和生活源;扬州市大气污染物重要性排序结果依次为:NO_x、SO_2、PM_(2.5)、PM_(10)、NH_3、VOCs和CO,主要污染物为NO_x、SO_2、PM_(2.5)和PM_(10)。In order to focus on the existing air pollution sources emission inventory and make an effective analysis, it＇s nec-essary to determine the main air pollution sources and pollutants, therefore the general principles and calculation methods of the importance ranking of air pollutants and pollution sources are formulated. Comparison and analysis were made among Beijing, Tianjin, Shanghai, Hangzhou, Guangdong Province and the Pearl River Delta which has conducted the emission study of NOx, SO2, PM（2.5）, PM（10）, NH3, VOCs and CO, and the importance ranking results of regional pollution sources and pollutants were obtained using the methods of equivalent pollution load ratio and Dixon test method. Taking Yangzhou City as an exam-ple, the importance ranking of air pollution sources are industrial sources, life sources, agricultural sources, mobile sources and other sources, with industrial and life pollution sources as the major pollution sources. The importance ranking of air pollu-tants are NOx, SO2, PM（2.5）, PM（10）, NH10, VOCs and CO, with NOx, SO2, PM（2.5） and PM（10） as the major pollutants.
