Analysis of Environmental Air Quality Characteristics and Key Regions in Guangxi During the 13th Five Year Plan Period
In order to understand the environmental air quality of Guangxi during the 13th Five Year Plan period and scientifically plan the air pollution prevention and control work of Guangxi during the 14th Five-Year Plan period,the pollution characteristics of fine particulate matter(PM2.5)and ozone(O3)were analysed by comprehen-sive index method and coefficient of variation method.The results show that in the 13th Five-Year Plan period,Guangxi's ambient air quality showed an overall improvement trend,and the pollution level was mainly light pol-lution.PM2.5 was still the most important pollutant affecting Guangxi's atmospheric environment quality.Ozone pollution showed a rising trend,and the characteristics of compound air pollution were prominent.During the 13th Five-Year Plan period,the variation degree of PM2.5 concentration in 14 prefecture-level cities in Guangxi was un-evenly distributed,and the variation coefficient of O3 concentration was generally smaller than that of PM2.5 con-centration.The spatial distribution shows that the air quality in the three coastal cities and western Guangxi is rel-atively good,while the air quality in Guilin,Liuzhou,Laibin,Guigang,Yulin,Wuzhou,and Nanning is relatively poor,which needs to be paid attention to in the prevention and control of air pollution.
