Coupling Correlation Between Urban Expansion And Resources-environment Evolution And Vulunerability Analysis

Relationship between urban development and resources environment evolutionand its vulnerability is one of the important research fields of the current academiccircles. With the speeding up of urbanization process in China, the development ofcities, especially in big cities expand at an accelerating pace, lead to the consumptionof resources environment and its pressure increa sing, vulnerability problem appearedcontinuously,this to be a reality obstacles of urban sustainable development,Therefore, the study of urban development and resource environment problem inrapid urbanization is particularly urgent.Changchun is a typical industrial city in China, In recent years, with theadvancement of economic development and urbanization process, urban continues toexpand,and its scale increasing,at the same time, the rapid development of the cityalso has a lot of pressure on resources and environment system, It also has certainrepresentativeness in the whole country.The paper take the Relationship between urban development and resourcesenvironment evolution as the main line,and ChangChun as a case city.it furtherstudied the coupling relationship between urban development and resourcesenvironment evolution and vulnerability influenced by urban development, Torevealed the interactive variation rule of urban development and resourcesenvironment evolution,and provide the reference and advice for Changchun tooptimize the way of urban development、Strengthen the resources environmentconstruction、promote Urban sustainable development. the thesis is organized into sixparts as following:The first part is the introduction,presented the research background and researchsignificance,reviewed the related research advances at home and abroad,andintroduced the main contents, methods of route and overall framework of this study.The second part is the basic theory, focus on defined the main concepts and basictheory, on this basis,introducing the theory of PSR,and then build, simulate theinteractive mode bewteen urban development and resources environment.The third part is the basic analysis,study the pattern of urban development andcharacteristics of resources environment evolution in Changchun on the whole,itLaid the foundation for further study of relationship between urban developmentand resources environment evolution The fourth part is one of the main content of this thesis,analyzed the level of urbandevelopment and resources environment,and on this basis,studied the couplingcorrealtion between urban development and resources environment evolution by buildthe coupling and responsivity mathematical models,and discussed the the influencefactors.The fifth part is one of the main content of this thesis,it mainly discussed thevulnerability of resources environment under influence of urban development byelement extension model and comprehensive index method, further analyzes theimpact factor of it by build regression model,and Finally proposed measure forregulate vulnerability.The sixth part is the conclusion and prospect, mainly analyzed the mainconclusions of this paper, points out the deficiency,and look forward the valuableresearch direction.
