以长春市中心城区的5类共1658个服务设施网点为基础数据,基于ArcGIS软件平台,通过构建优势度、集中度、中心度等空间模型,基于集聚与扩散双重视角探讨了服务设施网点的空间区位特征。研究发现:首先,长春市中心城区的服务设施网点呈现出显著的核心区集聚特征,空间分布的紧凑性整体较高,“单一中心”分布模式明显;其次,各类服务设施网点均为显著的空间集聚分布特征,但不同类型服务设施空间集聚与扩散的水平存在显著差异,其中盈利型、综合型设施的集聚度高于福利型、生活型设施,中心性低于福利型、生活型设施;最后,指出了各类服务设施空间布局存在的主要问题,并相应地提出了其调控的路径。
Based on the data of 1658 service facilities in Category 5 of Changchun downtown area and based on the ArcGIS software platform, this paper explores the space of service facilities outlets by constructing spatial models of dominance, concentration and center, based on the two perspectives of agglomeration and diffusion Location characteristics. The findings are as follows: First of all, the service facilities in Changchun downtown area show a significant concentration of core areas with a high spatial compactness and a “single center” distribution pattern. Second, all kinds of service facilities outlets are Significant spatial agglomeration and distribution characteristics, but the different types of service facilities spatial agglomeration and diffusion of the level of significant differences, including profit-oriented, integrated facilities higher than the concentration of welfare-type facilities, life-style facilities, central less than the welfare type, life type Finally, the paper points out the main problems existing in the spatial layout of various service facilities, and puts forward the path of its regulation accordingly.
