摘　　要：分别在采暖期和非采暖期采集了长春市净月区与朝阳区的大气颗粒物,研究其污染特征的差异,并进行了形貌分析。结果表明:(1)净月区采暖期与非采暖期PM_(2.5)平均质量浓度分别为144.86、87.10μg/m^3,PM_(10)平均质量浓度分别为149.07、138.72μg/m^3;朝阳区采暖期与非采暖期PM_(2.5)平均质量浓度分别为234.48、110.01μg/m^3,PM_(10)平均质量浓度分别为275.07、147.50μg/m^3。整体上,非采暖期大气颗粒物浓度低于采暖期。(2)无论是采暖期还是非采暖期,净月区PM_(2.5)与PM_(10)浓度均明显低于朝阳区。(3)净月区采暖期大气颗粒物来源主要是柴油尾气、燃煤源与生物质燃烧;非采暖期,机动车尾气、建筑扬尘、土壤扬尘与某些工业排放对大气颗粒物贡献较大。朝阳区大气颗粒物来源较净月区复杂,这与两个区不同的地理位置和不同功能有直接的联系,建筑扬尘对于朝阳区大气颗粒物的含量有较大的影响。Atmospheric particulate matters during heating and non-heating periods in Jingyue and Chaoyang Districts in Changchun City were sampled to study the pollution characteristics and morphology characteristics were also analyzed. The results showed that： （1） the average concentranons of PM2.5 in Jingyue District during heating period and non-heating period were 144.86,87.10 μg/m^3, and the average concentrations of PM10 were 149.07,138.72 μg/m^3 ,respectively. The average concentrations of PM2.5 in Chaoyang District during heating period and non-heating period were 234.48,110.01 μg/m^3 ,and the average concentrations of PM10 were 275.07. 147.50 μg/m^3 , respectively. Overall, the concentration of atmospheric particulate matter during non-heating period was greater than that of heating period. （2） For heating period and non-heating period,the concentrations of PM2.5 and PM10in Jingyue Distrcit were significantly lower than that of Chaoyang District. （3） In Jingyue District.the main source of particles in heating period were diesel exhaust, coal and biomass burning, while vehicle exhaust, construction dust. soil dust and some industrial exhaust had more contribution to the concentration of particles in non-heating period. The source of atmospheric particulates in Chaoyang District was more complex than Jingyue District.which was directly relative ro different geographical locations and different functions. Construction dust had great influence on the content of atmospheric particulates in Chaoyang District.
