摘　　要：大气气溶胶是影响大气环境的主要污染物之一,在大气污染过程中,大气气溶胶粒子污染在其中占有重要的地位。通过FTIR系统检测合肥冬季气溶胶粒子中的无机离子成分,表明合肥地区冬季气溶胶的源与气溶胶的粒径有关:粒径小于2.5μm的气溶胶细粒子,主要来源于化石燃料燃烧、饥动车排放等人为污染排放源。而在粒径大于2.5μm的气溶胶中,矿石含量比较高。The aerosol is one of the major pollutant components in the atmosphere. And the aerosol has a significant impact in the process of air pollution. The component and distribution of inorganic ions detected by FTIR show that the ambient aerosols source is related to the diameters of aerosols in Hefei. In winter, when the diameters of aerosols are smaller than 2.5 μm, the human activity is the main source, such as waste dumping, landfills and the exhaust gas from the vehicle. When the diameters are larger than 2.5 μm, the ore is the main source
