Research On Urban Spatial Structure Evolution Character Of Changchun-jilin Metropolitan Area And Optimization Path

In the era of rapid economic globalization and urbanization, polycentric metropolitan area across districts modern integration of urban functions to a certain extent the evolving mainstream urban tissue gradually becomes universal. “Changchun-Jilin Metropolitan Area”(CJMA) as a kind of organization of city spatial proximity, functions are closely related, and integration advantages superior based integrative development of urban district. Papers from CJMA are urban space structure optimization of background, and meaning, starts with, in on urban district, and city space organization, basic concept and theory integrated analysis, analysis on CJMA are urban of development background, space structure optimization of staged divided, and combines CJMA urban district actual carried out has on future space structure optimization of active exploration, hopes can on CJMA are urban in future East North domain economic cooperation and Jilin province new town of process in the up to corresponding of role.First part describes the background and significance of the study, pointed out that study on urban spatial organization framework and the evolution of the core research themes of urban geography and urban and rural planning and research. Defines the basic spatial categories of CJMA area, and describe the structure of the thesis framework.The second part of the metropolitan area and urban spatial structure of related concepts and the main research trends of urban spatial organization in China and abroad, also contain relevant theories.The third part started the research from CJMA city spatial structure evolution, starting with urban characteristics of spatial pattern of CJMA raised, and CJMA development present situation and conditions, sketch out the future spatial optimization of structure of CJMA.The last part is the conclusion part, it has summarized the main conclusions of the study on urban spatial structure of CJMA, and future research directions, as well as the innovation and shortcomings.
