【摘要】：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。
[Abstract]:Based on the data of 1658 service outlets of 5 types of facilities in the downtown area of Changchun, based on the ArcGIS software platform, the spatial models of dominance, concentration and centrality are constructed. Based on the dual perspective of agglomeration and diffusion, this paper discusses the spatial location characteristics of service facility network. Firstly, the service facility network of Changchun city center shows the characteristic of core area agglomeration. The compactness of spatial distribution is relatively high, and the distribution pattern of "single center" is obvious. Secondly, all kinds of service facilities are significant spatial agglomeration distribution characteristics, but there are significant differences in the level of spatial agglomeration and diffusion of different types of service facilities, among which the profit-making type. The concentration degree of comprehensive facilities is higher than that of welfare type, life type facility, centrality is lower than welfare type, life type facility; Finally, the paper points out the main problems existing in the spatial layout of various service facilities, and puts forward the adjustment and control path accordingly.

【正文快照】： 快速城镇化背景下如何满足愈来愈多城市人口的服务需求,成为当前摆在政府与规划部门面前的重要课题。转型时期中国的服务设施供给由政府主导转向市场驱动,服务设施过度集聚于城市核心区等某些特殊区域,出现了空间分异、配置失衡等问题[1-2]。城市服务设施是满足于社会大众服务
