| In recent years,with the gradual acceleration of urbanization and industrialization,the economic level of anhui province has been continuously improved.However,along with these developments,a series of environmental problems have been brought about,such as the increase of pollutant emissions,frequent haze phenomena and the hindering of sustainable development.Environmental pollution has always been one of the most concerned problems of human beings,which is related to the national economy and people’s livelihood.At present,the research on environmental pollution is more,but less on social economic research,and mostly the analysis is from the perspective of one or two influence factors,and there are few analysises done the job in a most comprehensive path.And most of the study,the environmental pollution index is relatively single,at the same time the choice of model mainly adopts linear model and the nonlinear model of a given equation,but these models need a suppose that there is some relationship between the dependent variable and independent variable beforehand,which seems to be not persuasive.Therefore,based on the existing research results,this paper studies the influence of various factors on the environmental pollution in anhui province from the perspective of social and economic aspects,so as to provide a scientific basis for the treatment of environmental pollution in anhui province and a reference for other regions to deal with environmental problems.Firstly,this paper uses factor analysis method to construct a comprehensive evaluation index system to calculate the environmental pollution degree index of Anhui Province from 1995 to 2017.The comprehensive score of factors is taken as the environmental pollution degree index of Anhui Province.Combined with descriptive statistical analysis,the present situation of environmental pollution in Anhui Province is analyzed.The results show that the environmental pollution degree of Anhui Province is gradually aggravated as a whole;secondly,Kriging takes the PM2.5 concentration as the main research object in Anhui Province in 2018 to analyze the temporal and spatial variation law of environmental pollution.Finally,taking the environmental pollution degree index of Anhui Province as dependent variable,this paper explores the level of en vironmental pollution and economic development,foreign direct investment,urbanization,industrial structure,and investment in science and technology in Anhui Province through the generalized additive model method(GAM).Whether there is an influence relationship between factors such as entry and ecological construction,and what role it plays in environmental pollution in Anhui Province.The results showed that:In 2018,the average concentration of PM2.5 in Anhui Province was 49,which had a significant:U" monthly variation pattern and seasonal characteristics of high in winter and low in summer;the concentration of PM2.5 in northern Anhui Province was higher than that in southern Anhui Province;Environmental pollution in Anhui Province is mainly affected by the level of economic development,urbanization and investment in science and technology,and there is a non-linear relationship between environmental pollution;environmental pollution increases with the increase of per capita GDP growth rate,but when the growth rate reaches about 0.2,environmental pollution will decrease with the increase of growth rate;environmental pollution will increase rapidly with the increase of urbanization rate.After that,it will decrease,but when the urbanization rate reaches 0.2,the environmental pollution will increase with the increase of urbanization rate.At first,with the input of science and technology,the environmental pollution will change slowly and increase slowly.When the expenditure on science and technology reaches about 0.08 of GDP,the environmental quality will begin to improve. |
