摘要
根据延安市城区2001—2010年的大气污染监测资料，选取SO2，NO2，TSP作为评价因子，参照我国环境空气质量标准，运用模糊综合评判的方法，建立各污染物的隶属函数和权重集，计算出各污染物的隶属度和权重分配系数，进而对延安市的大气环境质量进行评价。
According to the atmospheric monitoring data of Yan＇an city from 2010 -2010, selecting SO2, NO2, TSP as evaluation factors, consulting the ambient air quality standards and calculating the weight, distribution coefficients of weight, grade attachment of atmospheric pollution factors, and evaluation of Yan＇an atmosphere environment quality. The results indicated that Yan＇an ambient air quality in 2001 and 2002 was III grade, which was at the moderate level of pollution. But the air pollution improved year by year. In past ten years, Yan＇an atmosphere environment quality reached II grade in 7 years, and it achieved I grade in 2006. Before 2003, TSP was the main factors that restrict Yan＇an atmosphere environment quality.
