Research On The Correlativity Of Population Distribution And Commercial Spatial Structure Of ChangSha City

Urban spatial structure is the spatial reflection which a variety of social, economic activities reflected in the geographical space. A variety of factors in the city constitute a system of interaction, mutual influence, some elements of change will cause the overall combination of elements change, resulting of the deviation in the growth process of urban spatial structure. Man is both producers and consumers. The consumers’demand is the direct pulling power of the commercial development, changes in population distribution and consumption directly affects the formation of the urban commercial spatial structure. As the most active in the urban space development and have a significant impact on urban space development pattern change, population and business related closely. Study of correlation between urban commercial spatial structure and population distribution can help people improve the consciousness of the rational deployment of commercial branch. It also enables the basic trend of development of commercial space to adapt to the changes in the distribution of the population, to prevent the blind development of commercial enterprises, redundant construction, operation chaos, overlapping distribution and so on. It is conducive to play the guiding role of urban planning under the condition of market economy, reduce business facilities spatial distribution of reasonableness and imperfect, gradually establish corresponding to changsha city economic development, urban construction, rational layout, complete function, unified open, competitive and orderly modern city commercial space structure system.Changsha is the important capital cities and regional central cities in the Midwest. Its economic development has been at the upper level in the major capital cities in the Midwest,and ranking situation is similar to the other Midwest cities.It represents the development of major capital cities in the Midwest. Changsha spatial structure of concentrated development along the river in most cities in China have strong representation. Based on GIS spatial analysis method as the main research method, it focus on the evolution process and characteristics of the population distribution and commercial spatial structure.Selection of changsha city as the object of empirical study, it study on the correlation of the evolution of the population and commercial space, reveal the mechanism of population impact on commercial space structure evolution, and build the new mode of coordinated development. First of all, the articles collated and summarized data on the the Changsha population and commercial space, clarity the evolution characteristics of Changsha population distribution and commercial space structure. Secondly, using the GIS spatial analysis method, it clear correlation between population and commercial space development. By making a comparison of population distribution center and commercial space center, it summarizes the mismatch phenomenon in the evolution of the population distribution and commercial space. The main problems of Changsha commercial space layout of are pointed out, and update the commercial network planning, perfect the system of the commercial space, the construction of independent evaluation mechanism of the urban planning management, proposes reasonable suggestions of commercial network optimization configuration suitable for population distribution in changsha.
