Abstract

Urban air pollution is an urgent problem to be solved in the process of rapid urbanization and economic development in China. Based on the daily average data of urban air quality index of Henan province from 2015.1 to 2018.12, this paper utilizes cluster analysis, trend surface analysis and centralizing evolution analysis methods to study the spatial distribution characteristics and evolution pattern of urban air quality in the province. The results show that the air quality in the province presents five air quality systems, which seriously relate to the terrain, the air quality index of the northern cities has always been higher than that of the southern cities, with the latitude increases, the air quality index gradually increases, and the increase rate in the middle region is significantly higher than that in both sides. The province weathers, in the study period, shows 4 grades as good & moderate, lightly polluted, moderately polluted and heavily polluted. Lightly polluted weathers first appear in central and southern cities, moderately polluted and heavily polluted weather first appear in the northern cities, and then spread to the rest cities of the province.
