Urban Spatial Structure by Service Facilities Distribution :A Case in Main Districts of Changchun
This paper adopts the service facilities layout perspective to discusses the urban space structure in main districts of Changchun,which is based on the data of 6 classes,a total of 2418 services networks in main districts of Changchun.We have used ArcGIS software platform to cite the Kernel Density,Standard Deviation Ellipse and Layer Analysis spatial econometric model.The result shows that:The urban land use structure reflected by the service facilities network is given priority to with "single center" agglomeration,The city's periphery has appeared the phenomenon of diffusion and re agglomeration.The urban land use structure reflection shows a "Axial type" and "Saltatory type" diffusion trend,and on the whole has formed four levels of services cluster center;And the layout of the service networks exists deviation with construction land,and the service networks have the higher feature in concentration than those construction land.At the same time,the distribution of service facilities is obviously insufficient in Southwest and northeast direction.Service facilities' high density areas are mainly gathered within "three-circle".Compared with the expansion of the construction land,the service facilities have showed obviously lag.Lack of those service facilities in the Periphery of main districts has caused the problems of the lack of urban function.
