Analysis On Evolution Mechanism Of Urban Spatial Structure Modern Bohai Region Coastal Cities

Urban spatial structure is urban spatial position of each element and the interlinkages between them. Urban spatial structure has an important impact on the efficiency of city operations. Urban transport, environment, land, macroeconomic and other cities issues are closely linked with urban spatial structure.In recent years, China’s urbanization and industrialization process accelerated, fast-growing city size, Accelerated evolution of urban spatial form, the breadth and depth of research has emerged as the new changes. As China’s economic restructuring, the impact of the knowledge economy and the new economy of the urban development of deeply increasing, institutional innovation and economic transformation of urban spatial form evolution has played an important role in promoting. Factors and dynamic mechanism is also showing intricate features. During this period, China’s major cities starting from the development model of concentration to the development model of centrifugal, Spatial form of representation of urban social, economic, and environmental development has become the problem must be solved.This thesis was summarized the theory of the development of urban spatial structure domestic and abroad, chose Tianjin as an example of the Bohai region, under the guidance of the theory of urban planning, Learn from urban geography, urban land economics and other disciplines theoretical methods, combining both qualitative and quantitative research methods, Research on urban spatial structure, characteristics and mechanisms of urban spatial structure evolution. This thesis studies the evolution of urban spatial structure in Tianjin, Analysis on urban spatial structure evolution mechanism and characteristics of different stages of urban development, Analyze the trends of Tianjin urban space in the future. On this basis, this thesis attempts to summarize generally applicable urban space model to the coastal city for future development, and also to provide reference for other coastal development.
