- Abstract
This paper attempts to reveal the characteristics and influencing factors of air pollution in Sichuan Basin. To solve the air pollution problem and gain some implications, six criteria air pollutants and six meteorological parameters were counted; local statistical data at the provincial level were acquired in 2018; the temporal-spatial distribution contour map of monthly mean PM2.5 concentrations was drawn; the monthly trends of PM2.5, PM10, and O3 were analyzed; the monthly mean six criteria air pollutants and six meteorological parameters at the basin scale were established by Spearman's correlation analysis and hierarchical agglomerative cluster analysis (HACA); and the annual mean air pollutants and local statistical data at the city scale were calculated by Spearman's correlation analysis. The results implied that (1) PM2.5, O3, and PM10 were the dominant air pollutants; (2) Chengdu (CD), Zigong (ZG), Deyang (DY), Mianyang (MY), Yibin (YB), and Dazhou (DZ) were the cities with the worst air quality; (3) December, January, and February were the worst months; (4) the air pollution tends to spread from type-I cities to type-IV cities; (5) temperature and precipitation were important predictors which were correlated with pollutants strongly; and (6) the main sources of air pollution originated from anthropogenic activity, such as PM2.5 from the emission of industrial enterprises and PM10 from vehicle traffic. Finally, we give some recommendations.
