摘　　要：空气污染指数(API)是一种综合反应和评价空气质量的指标,分级表征空气污染程度和空气质量状况。利用上海市环境监测中心收集的上海市2006～2011年各个区的API指数,对API指数进行时间序列分析和空间分析,包括近6年来API的年变化、季节变化以及比较上海市市区和郊区的API值。结果表明:上海市的空气污染状况在2006～2011年期间得到改善;夏季的空气质量最好,春季最差;空间上存在城郊差异,郊区API指数低于市区,金山区空气质量最好,普陀区和宝山区质量较差。API （Air Pollution Index） is a comprehensive index which reflects and evaluates air quality and is classified to represent air quality and pollution condition. According to the API of different districts in Shanghai during 2006 -2011 collected from Shanghai Environmental Monitoring Center, time series and spatial analysis are conducted which included annual changes, seasonal changes and comparison on urban and suburban API value during past 6 years. The results showed that the air condition of Shanghai had improved. The air quality was the best in summer and the worst in spring. Spatially, the air quality is different in rural area and urban area. The API in the suburban was better than that in the urban. The air quality in Jinshan district was the best while it was quite worse in Putuo and Baoshan district.
