The Typical Functional Coupling Between Areas In Changchun City

The city spatial structure is always the key and hot research in human geographyscholars. Coupling between the function of urban area is a basic research to reveal theevolution of urban function, morphology, evolution mechanism and explore thebinding relationship. Multi-angle study on the evolution of the coupling relationshipof cities has a positive significance on urban spatial structure and spatial form of cities.It helps us to define the influence of the city development and the change of the powerfactor, and the interaction among.In this paper, we take Changchun City as an example. Select4typical functionregions, focus on the coupling relationship between the industry, residential,commercial and transportation space in this region, and reveal the problems offunction space coupling in Changchun City. Aiming at the problems existing in thefunction space, we put forward optimization countermeasure. This paper is dividedinto seven chapters.Chapter I: Introduction. This paper introduces the research background, researchsignificance, research objectives, emphasis and difficulty of research ideas andresearch methods.Chapter II: Overview of related theoretical research, Define the concept of cityfunction zone, the coupling relationship and the internal spatial structure, Introducesthe location theory, the theory of city function zoning, space theory, interaction theory,and city space theory. The related research at home and abroad is summarized.Chapter III: The analysis of typical regional of Changchun City. First introducedthe general situation of Changchun City, the second part defines the selection range oftypical function region, and tells the necessity of selection, at the end, analysis theblock.Chapter IV: Analysis of the coupling relationship between the typical function ofChangchun City. Use land area proportion, number of plots, plots of land area, theproportion of first degree,4block index, Shannon-weaver diversity index and thediversity of the average degree to analyze the coupling relation between industrialspace, residential space, service space, and traffic space. Analyze the interactionbetween each functional space. Chapter V: Analyze the coupling relationship problems of typical function regionof Changchun city. Summarizes the problems of industrial space, living space, servicespace, and traffic space.Chapter VI: Discuss the optimization countermeasures of typical function regioncoupling relationship of Changchun City. Analyze the city function spaceoptimization principle, and proposes the optimization strategy of city function space.Chapter VII: Conclusion and Outlook. Summary the above research, and pointout the deficiencies that may exist, and on this basis, make a further prospects of theresearch direction in the future.
