The Research On The Relationship Between Urbanization And Eco-environment Of Changsha-Zhuzhou-Ziangtan

Since the reform and opening-up policy has been implemented,China's major cities go into the rapid development stage of urbanization.Chang-Zhu-Tan city Group is the national experimental zone,which is the first to carry out the "Two-oriented" social construction and the new urbanization construction is one of the core tasks of "Two-oriented" social construction.How to build a new urbanization is the key to "Two-oriented" social's construction.However, while rapid urbanization, industrialization and urbanization changing a profound impact on the urban environment influence "Two-oriented" social in the construction and quality of life for urban residents,the environment is increasingly plagued booming city. This research will be based on the importance of the urbanization and the serious environmental issues in the context of rapid urbanization to identify goals-The Research on the Relationship between Urbanization and Eco-environment of Changsha-Zhuzhou-Xiangtan.First of all,the evolution of urban theory, the ecological city theory and the theory of the ecological environment as the main analytical tool,initially built a process of urbanization and ecological environmental impact mechanism of the theoretical framework,analyzing the fast urbanization process in the environmental response mechanism.Secondly, relying on the above theoretical framework,using coupled system coordination degree, unit root test,panel cointegration test and DOLS estimation methods of the Chang-Zhu-Tan city and the main pollutants in the process of regression relationship between the obtained corresponding conclusions:1.The coupling model of coordinated development degree of Chang-Zhu-Tans'urbanization in the past 10 years coupled with the current situation of ecological environment in the analysis,which showed broadly similar trends,but the coupling of Changsha,was obviously higher than the coordinated development of Zhuzhou City and Xiangtan City,Changsha City coupling coordinated development degree is breaking-in period, while the Zhuzhou and Xiangtan in the tempering stage, urban development and ecological environment interaction is not very satisfactory.2.1989 to 2008 the level of the consolidated city and the major environmental pollutants SO2,NOx,and TSP composition of the panel data has passed the unit root test and cointegration test to prove they do exist between the long-term stability of the cointegration relations, DOLS estimates significantly(SO2 and TSP),as can be seen from the equation,along with environmental pollutants and raising the level of urbanization has decreased, namely:Chang-Zhu-Tan's promotion of urbanization can improve the ecological environment assumptions proving to be established.Finally, based on this paper's theoretical analysis,empirical conclusions and environmental policies of the current propose policy recommendations in favor of the urban system and the coordinated development of ecological systems, Two-oriented "society's construction of new cities and eco-city construction.
