摘　　要：随着我国老龄人群体的扩大,构建完善的养老服务设施体系对推进社会适老化改造具有有重要意义。以益阳市为研究对象,借助ArcGIS软件,运用平均最近邻、标准差椭圆、核密度分析等GIS空间分析方法和栅格计算法,对该市养老设施空间格局特征及其可达性进行了分析。结果表明:益阳市养老设施的空间分布整体上呈集聚特征,其中,中心城区集聚显著,其他县域呈块状分散特征;不同类型养老设施的空间分布差异显著,大部分围绕某一核心区域分布,也存在双核心分布特征;可达性时间大多在0.45 h之内,高可达性与路网密集区域高度重合,主要集中在中心城区。With the expansion of the elderly population in our country,it is of great significance to build a sound elderly care service facility system to promote social senior-friendly transformation.Taking Yiyang City as the research object,with the help of ArcGIS software,GIS spatial analysis methods such as average nearest neighbor,standard deviation ellipse and kernel density analysis and grid calculation method are used to analyze the spatial pattern characteristics and accessibility of elderly care facilities in Yiyang City.The results show that the spatial distribution of elderly care facilities in Yiyang City shows the characteristics of agglomeration as a whole,among which the agglomeration in the central urban area is significant,and the other counties show the characteristics of mass dispersion.The spatial distribution of different types of elderly care facilities is significantly different,most of them are distributed around a certain core area,and there is also a “double core” distribution feature.The accessibility time is mostly within 0.45 h,and the high accessibility is highly coincident with the dense area of the road network,mainly concentrated in the central urban area.
