Changchun Metropolitan Region Space Expansion And Nearly Domain Integration Research

Along with the further development of economic globalization, the competition betweencities is growing, more and more urban development present character of region andmetropolitan city become the mainstream in the world. Under this new background, thedevelopment of Metropolitan coordinating region presents some new trends. With centricityfurther enhanced, at the same time spatial diffusion of wide area and regional integrationdevelopment further. Metropolitan coordinating region spatial expansion process can directlyreflect the city population distribution, land use and industrial distribution, so based on theanalysis of Changchun metropolitan coordinating region regional formation, expansionhistory and the current situation, we discussed the further of Changchun metropolitancoordinating region how to extend and integration problems and predict the scale ofChangchun metropolitan coordinating region in the population, land use and the scale of theindustry in the future. Paper main body includes four chapters.First chapter is the introduction. To elaborate the study of the macroscopic backgroundon the expansion. From the concept of metropolitan coordinating region and urban integrationdevelopment, compared the domestic and foreign about the metropolitan coordinating regiondevelopment stage, the change of space structure, and urban spatial extension of pattern.The second chapter is the basic theory expound, mainly expounds the correlation theoryof metropolitan coordinating region spatial expansion and city spatial interaction.metropolitan coordinating region extension of theory mainly from the spatial patterns of urbanland use theory, residents demand the theory of land use and traffic accessibility affects landuse theories to analysis; And urban spatial interaction theory that are derived from theNewton’s law of universal gravitation，Reilly-Kang firth model, gravity model and potentialmodel. The urban spatial interaction model, the gravity model is one of the types of analysisand forecast space flow theory, the potential model is not primarily solve the interaction itself,but the opportunity of interaction between different social groups or probability, theopportunity is because of its size and location.The third chapter on the analysis of Changchun metropolitan coordinating regionextended on the basis of the history and current situation characteristic, from the naturalgeographical conditions, the urban transportation network, city regional structure, urbanplanning and policy guidance, etc and expounds the influence of Changchun metropolitancoordinating region mechanism of spatial extension, the accumulation and dispersion ofChangchun metropolitan coordinating region city function and city land space extension ofpredicting the Changchun metropolitan circle in the size of the population, industry, land use,etc.Chapter four in determining nearly urban integration in the aspects of population,commuting, land use indexes, which satisfies the condition of the surrounding villages andtowns, so as to determine the spatial scope of the Changchun metropolitan coordinatingregion.
