摘要
通过采集上海市养老机构、养老床位及上海市街镇、道路的基础空间数据,基于ArcGIS平台采用平均最邻近指数、核密度分析、均值比及改进的两步移动搜索法,实证分析上海市养老机构的空间分布特征和可达性水平。结果表明:(1)上海市养老机构与老年人口的分布基本实现空间耦合。(2)养老机构呈现市中心高度集聚的分布模式,养老床位数则由市中心到郊区呈现集聚—分散的格局。(3)94%的街镇养老机构提供基础服务的经济可达性水平大于1。(4)私家车出行方式的空间可达性最好,且61.29%的街镇能够在1h交通距离内提供养老服务。
Against the background of accelerating into aging society in China,it is the hotspot of academic research and policy practice to improve spatial distribution efficiency of the elderly care institutions.This study establishes a spatial database including pension institution,endowment beds and towns’positions,traffic lines of Shanghai.Adopting the average nearest neighbor index based on ArcGIS platform,nuclear density analysis and improved two-step floating catchment area method,it empirically analyzes the spatial distribution characteristics of Shanghai’s elderly care institutions,and their accessibility from a spatial and economic perspective.The results show that:(1)The distribution of the elderly care institutions and the elderly population basically achieve spatial coupling.(2)The elderly care institutions are highly concentrated in the city center,while the distribution of elderly care beds is concentrated-decentralized from the city center to the suburbs.(3)The level of economic accessibility to basic elderly care services has been greater than 1 in 94%of the streets and towns.(4)The spatial accessibility of private car travel is the best,and 61.29%of the streets and towns can provide elderly care service within one-hour traffic distance.
