摘　　要：根据历史和现状监测数据,分析了苏北某县主要污染物的浓度特征,同时利用源清单法和受体模型法研究了该县主要大气排放源的空间分布及颗粒物来源解析。源解析结果表明,PM_(10)主要来自建筑尘,其贡献率可达到31.14%;其次是煤烟尘,贡献率为15.84%。对于PM_(2.5)来说二次无机气溶胶以及煤烟尘是最主要的来源,其贡献率分别为25.9%、22.68%,其次是机动车尾气,贡献率为19.49%。According to the historical and current atmospheric environmental monitoring data of a county in North Jiangsu,we analyzes the characteristics of major pollutants. With the emission inventory and receptor model（ CMB）,We come to know the spatial distribution of all atmospheric pollutants and fine Aerosol Source Apportionment. The results show that particulate matter,especially fine particulate matter pollution is one of the major problems. The receptor model results show that PM10 mainly come from the construction dust,its contribution rate can reach 31. 14%,followed by coal smoke,accounted for 15. 84%; For PM2.5,secondary inorganic aerosols and coal dust are the main sources,the contribution rate were 25. 9% and 22. 68%,followed by motor vehicle exhaust,the contribution rate is 19. 49%.
