摘要
运用模糊数学方法,选用SO_2,NO_2,PM_(10)作为评价因子,参照大气环境质量标准,通过计算污染因子权重、权重分配系数和隶属度,对生态保护发展区大气环境质量进行评价.模糊数学综合评价结果表明,生态保护发展区"十二五"期间主要污染因子为PM_(10),次要污染因子由SO_2逐渐变为NO_2,NO_2污染呈现上升趋势应引起警惕.大气环境质量基本上处于清洁和轻度污染水平,且大气环境质量有逐年改善趋势.
Consulting the standards of atmospheric environment,the atmospheric environment quality of take ecological protection zones have been evaluated by means of fuzzy mathematics,selecting SO_2,NO_2,PM_（10） as evaluation factors to calculate the weight of distribution coefficients and grade attachment of atmospheric pollution factors.The results of comprehensive evaluation indicate that the atmospheric environment of take ecological protection zones were clean and light pollution,and it was improved year after year.
