运用模糊综合评判的方法,选取二氧化硫、二氧化氮和可吸入颗粒物作为评价因子,参照我国环境空气质量标准,通过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,进而对达州市空气质量进行模糊综合评判。并将模糊综合评判法与空气污染指数分析所得结果进行比较。
運用模糊綜閤評判的方法,選取二氧化硫、二氧化氮和可吸入顆粒物作為評價因子,參照我國環境空氣質量標準,通過建立各汙染物的隸屬函數和權重集,計算齣各汙染物的隸屬度和權重分配繫數,進而對達州市空氣質量進行模糊綜閤評判。併將模糊綜閤評判法與空氣汙染指數分析所得結果進行比較。

By means of fuzzy mathematical comprehensive evaluation,this paper assesses the air quality in Dazhou.Selecting SO2,NO2 and PM10 as evaluation factors and consulting the standards of air quality,the membership functions and the weights of different pollutants are set up.Then the degree of membership and weight distribution coefficient are calculated,by which air quality of Dazhou City is evaluated.The results of the methods of fuzzy mathematical comprehensive evaluation and of Air Pollution Index are compared.
