The Research Of Coupling Relation Between Urbanization And Eco-Environment In Daqing City

Urbanization and ecological environment has important influence on urban development.The rapid development of urbanization promotes the urban development and the ecologicalenvironment problems restrict urban development. And there is the interactive couplingrelation between two. Urbanization has threatened to limit the role of the ecologicalenvironment. Ecological environment for the development of urbanization have tiedinhibition. Urbanization is rapidly changing world, while environment is facing the troubledglobal, which is not conducive to the sustainable development of cities in21stcentury.Therefore, it is particularly important to handle properly the relationship betweenurbanization and ecological environment and explore the coupling law between them in orderto the city’s sustained, healthy and orderly development. As an important oil region of Daqingcity, the development of urbanization is rapid and ecological environment is facing a hugechallenge.Given this, I determine the research of coupling relation between urbanization andeco-environment in Daqing city as the thesis of this paper.The level of urbanization and ecological environment quality were analyzed by factoranalysis in Daqing. Make use of correlation analysis between urbanization andeco-environment in Daqing by grey correlation model. The coupling between urbanizationand eco-environment in Daqing were studied by the coupling coordination degree model andGM (1,1) prediction model, in order to promote the city of daqing city and ecological systemcoordinated development of urbanization, which provide scientific reference.The results showed that (1)1995-2012, the composite level of urbanization of daqingcity roses overall trends. Although the overall development situation of urbanizationcomprehensive level in Daqing city is good, their internal system development is not balanced.In the process of urbanization, population urbanization level was significantly higher than theurbanization level of of economy, land and society.(2) Ecological environment also showed arising trend, but the ecological environment rose more slowly. From1995to2010, theecological environment level and ecological environment governance have been lower thanthe ecological stress; in2011-2012the ecological environment level and ecologicalenvironment governance improve, the ecological stress drop. Its internal system developmentis not balanced.(3) Urbanization and eco-environment coupling coordination degree ofdaqing city increased from0.025to0.681in1995-2012. Although the value of coupling coordination degree has improved, the overall value is low. The unbalanced development ofurbanization and ecological environment in Daqing city led to that the coupling coordinationdegree is low and present diversity.(4) The unbalanced development of urbanization andecological environment in daqing city will continue to exist, coupling relationship betweenurbanization and eco-environment will be weakened in the future a period.
