Abstract：In order to focus on the existing air pollution sources emission inventory and make an effective analysis,it's necessary 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,PM2.5,PM10,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 example,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 pollutants are NOx,SO2,PM2.5,PM10,NH10,VOCs and CO,with NOx,SO2,PM2.5 and PM10 as the major pollutants.
