摘　　要：利用模糊评价模型对现有的空气污染指数的评判标准进行改进。首先以西安市2008-2012年的空气质量数据为例,应用灰色模型的理论知识,找出影响空气质量最大的因素是NO2,其后是PM10和SO2。然后利用层次分析法对污染的途径进行分析,得出汽车尾气排放对空气污染的影响最大,其次是燃烧,并对此提出相应的建议。The existing air pollution index criteria is improved by the fuzzy evaluation model in this paper. First of all ,taking the air quality data of Xihn from 2008 to 2012 for example, the factors that affecting the air pollution is analyzed by means of the gray model and the result is obtained that the order of affection is NO2, PM10, S02, succes- sively. Secondly the approach of the pollution is analyzed by analytic hierarchy process, the largest influencing factor to air pollution is the vehicle emissions followed by the burning. And the correlative suggestion is proposed .
