| 摘 要： | 为了促进科学减排、精准防治大气污染，选取PM2.5、PM10、SO2、CO、NO2、O3作为评价因子，通过熵权法建立污染因子权重集，以扩展后的环境空气质量标准为基础，通过计算各评价因子的隶属度，对汾渭平原11个城市不同季节的环境空气质量进行模糊综合评价，得出各城市的大气污染水平及季节变化特征。结果表明:该地区各城市空气质量受季节影响变化大，春、夏、秋季空气质量明显优于冬季，PM2.5、PM10、SO2、O3为主要污染物，评价结果可客观全面地反映该地区不同季节环境空气质量状况。

| Abstract: | In order to promote scientific emission reduction and precise prevention and control of air pollution, PM2.5, PM10, SO2, CO, NO2 and O3 were selected as evaluation factors, and the weight set of pollution factors was established by the entropy weight method. Based on the expanded environmental air quality standard, the membership degree of each evaluation factor was calculated, and the rings of 11 cities in Fenwei Plain in different seasons were determined. The ambient air quality was evaluated by fuzzy comprehensive evaluation, and the air pollution level and seasonal variation characteristics of each city were obtained. The results showed that the air quality of the cities in this area varied greatly with the season. The air quality in spring, summer and autumn was obviously better than that in winter. PM2.5, PM10, SO2 and O3 were the main pollutants. The evaluation results could objectively and comprehensively reflect the air quality in different seasons in this area. |
