The Distribution Characteristics Of Haze Pollution In Anhui Province And Research Of Its Influence Factors

In 2013,the eruption of haze pollution in China made the haze pollution problem of China been focused in world.Anhui,as the province that economic is rising up,also constantly confronted with the smog pollution in the process of its economic development.The problem of haze pollution needs to be solved urgently.To solve this problem,this paper studies the situation and influence factors of haze pollution in anhui province,and tries to find ways to alleviate the haze pollution in Anhui province.This paper is divided into five parts.Firstly,the paper mainly introduces the research background and significance of this paper,the formation mechanismof haze pollution and summarizes the previous research about the haze pollution.Secondly,the paper introduces the natural condition and the development of social economy in Anhui province,including climate,topography,precipitation,administrative division,economic development,industrial structure,energy consumption,etc..and makes a preliminary judgment about the influence of natural factors on the haze pollution in Anhui.Thirdly,the paper studies the characteristics of time and spatial distribution ofthe haze pollution in Anhui province by using statistic method.The paper also carries on an exploratory analysis about the spatial correlation of smog pollution in Anhui province,including the global spatial autocorrelation and partial spatial autocorrelation analysis.The research finds that the haze pollution in Anhui province has obvious seasonal effect as well as the whole country.,The haze pollution in recent years,shows a high-low-high-low change trend,the cities with severe haze pollution mainly include hefei,huaibei,maanshan tonglin.The cities with light hazepollution mainly include huangshan,chizhou,xuancheng.The paper also finds that haze pollution in Anhui province has obvious spatial correlation,the increase of haze pollution in heifei will increases the haze pollution in the surrounding areas of heifei,there also has a low-low concentration area of hazepullution in huangshan,chizhou,xuancheng.Fourthly,the paper uses PM₁₀ concentration as explained variable,selects the size of the economic development,industrial structure,population density and other factors as expain variable,anaylzes the influence factors of hazepollution in Anhui province.By establishing models with time-fixed effects and modesl with individual-fixed effects,the paper studys the different effects of different influence factors to the haze pollution on the path of time and the path of cross section.The study finds that the influence of different factors of the haze pollution has different effect paths,the influence of population density to haze pollution mainly comes from the cross section path and has a positive impact,the influence of industrial structure and the actual use of foreign capital to haze pollution mainly come from time path and have positive influence.In addition to this,the paper divides Anhui into 3 areas,the sounth of Anhui?wannan?,the north of Anhui?wanbei?,the middle of Anhui?wanzhong?.By taking FGLS estimation method,the paper examines the different influence of these influence factors to haze pollution between the 3 areas.The study finds that the industrial structure have less effect on haze pollution in wanbei,the actual use of foreign capital has larger influence to haze pollution in wanbei.At the same time,the expense in science has obvious negative effect to haze pollution in wanbei,but positive effect in wanzhong.Finanlly,the paper summarizes the research conclusions of this paperand puts forward some suggestions about how to reduce the haze pollution concentration in Anhui province.
