摘　　要：以上海市2000—2013年间的环境空气质量监测数据为依据,对SO_2、NO_2、PM_(10)和pH进行统计分析。结果表明:SO_2质量浓度从0.061 mg/m^3下降到0.024 mg/m^3;NO_2质量浓度从0.090 mg/m^3下降到0.048 mg/m^3;PM_(10)质量浓度从0.099 mg/m^3下降到0.071 mg/m^3;但是,降水pH在4.39—5.19,酸雨率呈上升趋势。近14年上海市空气质量优良率为89.7%,冬季较差,夏季较好。从空间分布来看,城市中心区域PM_(10)污染远高于非中心区域,其中杨浦区、普陀区、徐汇区、黄浦区的空气质量较差,金山区、崇明县的空气质量最好。相关数据分析表明,上海市空气污染源主要是工业燃煤、建筑施工扬尘和机动车尾气。According to Shanghai＇ s ambient air quality monitoring data between 2000--20l3 ,the air quahty was statistically analyzed in terms of SO2 , NO2 and PM10 concentrations and pH. The results showed that the SO2 concentration dropped from 0.061 mg/m3 to 0.024 mg/m3 ,the NO2 concentration dropped from 0.090 mg/m3 to 0. 048 mg/m3 and the PMI0 concentration dropped from 0. 099 mg/m3 to 0. 071 mg/m3 ; but the pH of rainfall was 4.39--5.19 ,and the frequency of acid rains presented an ascending trend. In the past 14 years the good-grade rate of ambient air quality was 89.7% ,being better in summer than in winter. In terms of PM10 ,the central met- ropolitan districts such as Yangpu District, Putuo District, Xuhui District and Huangpu District were much worse than the non-central metropolitan districts such as Jinshan District and Chongming County that were the best in air quality. The related data analysis indicated that the coal-burning industry, dust-producing construction sites and automotive vehicles＇ exhaust gas were major air pollution sources in Shanghai.
