Description
Summary:The atmospheric environmental quality problem is one of the important issues concerned by domestic and foreign researchers. In this paper, a fuzzy comprehensive evaluation method of atmospheric environmental quality is provided. SO 2 , NO 2 , PM 10 , PM 2.5 , CO and O 3 were taken as evaluation factors, and Daniel trend test method, fuzzy comprehensive evaluation method and Pearson correlation analysis method were used to evaluate the atmospheric environmental quality and change trend in Zhangjiajie City from 2015 to 2020. The results showed that: 1) The atmospheric quality was Class I and optimized year by year; 2) Except for NO 2 , the concentrations of PM 2.5 , PM 10 , O 3 , SO 2 and CO all showed a downward trend, and the main pollutions affecting the atmospheric quality are transferred to NO 2 and O 3 . 3 ) There was a correlation between each pollutant, and the pollution levels in the four seasons were in order of winter > autumn > spring > summer; This study provided a scientific basis for the prevention and protection of atmospheric environment and the sustainable development of tourism in Zhangjiajie city.
