Research On Air Quality Status And Correlations Of Economic And Social Development In The Yangtze River Delta Major Urban

During three decades of reform and opening up, C hina’s economy has been developing rapidly, people’s living standards have been greatly improved. However, the rapid development of economy also caused damage to the environment, regional and complex air pollution problems long-term accumulation formed have become increasingly prominent, air is polluted seriously, air quality is deteriorated, polluted air affect the way people work, live, and even has on people’s health threat. After the great improvement of material living standards, people’s demand for clean air are more urgent, and the development of "green" and "eco development" is put forward by country, and effective improving the quality of the air has become a top priority, Therefore this paper uses the Yangtze River Delta as an example, which has an important strategic position in our country modernization, but regional atmospheric pollution is gradually emerging, pollution problems occur frequently. Make a reasonable evaluation of air qua lity status in the main city of the Yangtze River Delta, on the basis knowing air quality state, then analyse economic and social factors of influencing air quality, its Correlation degree with air quality. Select the main indicators of empirical research, which has a positive significance on urban development planning, decision-making, the urban air quality improvment.This paper is divided into six parts: the first chapter mainly introduces the research background, significance, research status, research content and innovation; The second chapter mainly introduces related knowledge of air quality and evaluation method, and the related theories and methods; The third chapter mainly introduces the natural and economic condition of the research object,the reason of selecting indexes and using fuzzy evaluation model to make air quality assessment of the main city in the Yangtze River Delta; the fourth chapter is the influencing factors analysis of panel data regression results, introduces the index selection and source, model construction, model stability,Cointegration test, model selection and regression analysis of influencing factors; The fifth chapter is according to the above analysis of the current status of air quality evaluation, and influencing degree of social and economic factors on air quality, in order to improve air quality, and puts forward the related strategies; The chapter six is summary and inadequate of this paper.Evaluate air quality of the main city in the Yangtze River Delta and research Social and Research on the relationship between air quality and major economic and social factors. Establish fuzzy comprehensive model of Evaluating air quality,and Panel Data Model of main economic and social factors. The results show that: in the Yangtze River Delta, the main urban air quality was in the corresponding grade III standard. Based on that, analyse influence level of the economic and social factors: the tertiary industry value has a positive impact on air quality; the population density, the per capita GDP, the industrial dust emissions and the second industry ratio have a negative effect on air quality; industrial dust emissions and the second industry ratio have a larger impact on air quality. This means that the air quality in the Yangtze River Delta air quality is still not optimistic. Economic and social factors that influence air quality can not be ignored. This provides a reference for policy makers to make decisions.
