摘　　要：于2011年在长春市的8个大气环境自动检测站上采集了采暖期和非采暖期的PM10受体样品,并针对市区内PM10的主要污染源道路尘、城市综合扬尘、土壤风沙尘、建筑尘、工业燃煤尘和机动车尾气尘等采集了PM10源样品。对源和受体样品中所含无机元素进行了分析测定,使用以化学质量平衡模型(CMB)为基础的二重源解析技术及其改进方法对长春市大气环境中PM10进行二重源解析研究。结果表明:改进后的二重源解析技术易于确定对PM10贡献大的各单一尘源,能更好的反映城市大气中PM10的主要来源,为制定长春市大气污染治理方案及重点污染源防治提供科学的技术支撑。PMl0 receptor samples of heating and non-heating periods were collected at the eight existing atmospheric environment automatically monitoring stations in Changchun in 2011. Main sources samples of PM10such as road dust, comprehensive urban dust, soil wind dust, construction dust, industrial coal dust and motor vehicle exhaust were collected in Changchun. Then inorganic elements contained in the source and receptor samples were analyzed and determined. This paper studied on source apportionment of PM10 in urban atmosphere of Changchun with improved source apportionment technique and its amending method based on the chemical mass balance model （CMB）. The result shows that the amending method of improved source apportionment technique is easy to identify the large single dust sources for the atmospheric particulate matter. The result reflected the main sources of PMl0 and provided the optimal technical support for the development of air pollution control measures and the prevention of key sources of nollution in Changchun.
