    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.
