摘　　要：运用模糊数学法以保定市为例,对2002年至2007年环境空气质量进行了综合评价,选用SO2、NO2、PM10作为评价因子,通过计算权重系数和隶属度对环境空气按照年度、季节、采暖期非采暖期分别计算。评价结果表明:保定市环境空气质量呈现逐年好转,SO2、PM10依然是保定市空气质量的制约因子,且NO2的权重逐步上升。In this paper,fuzzy comprehensive evaluation was applied to evaluate the air quality in Baoding City during the period of 2002 ～ 2007. Weight coefficients and membership grades of the atmospheric environment were calculated based on the data from the city＇s automatic sampling stations,including the variables of SO2, NO2 and PM10. The air quality was assessed according to the above calculated results of annual,seasonal,and heating period respectively. The assessed results showed predominate factor of air pollution is still attributed to PM10 and SO2,while air quality was improved during this period.
