安徽省养老机构空间分布特征及其分异研究

随着老龄化程度不断加深和传统养老观念的改变,机构养老逐渐成为满足老年人养老的方式之一。利用最近邻指数和核密度估计法探究安徽省养老机构空间分布特征,借助地理探测器模型探究其空间分异成因。结果表明:研究区养老机构空间分布呈现多核心集聚,形成以蚌埠市、淮南市和马鞍山市为中心的"品字型"分布;不同等级规模养老机构空间分布呈现不同特征,大型养老机构呈现双核心集聚特征,中、小型养老机构则呈现出多核心集聚特征;养老机构空间分异由多个影响因素共同作用产生。其中,老年人口数量对养老机构空间分布影响最大,植被覆盖率对养老机构空间分布影响最不明显。

A Study on the Spatial Distribution and Differentiation of Elderly Care Institutions in Anhui Province

With the population aging and the change of traditional elderly care concept, institutional elderly care has gradually become one of the ways of elderly care to meet the needs of the elderly. This paper uses the nearest neighbor index and kernel density estimation method to explore the spatial distribution of elderly care institutions in Anhui province, and explores the causes of their spatial differentiation with the help of geographic detector model. The results show that: the spatial distribution of elderly care institutions in the study area presents multi-core agglomeration, forming a "triangle-shaped" distribution centered around Bengbu City, Huainan City and Ma''anshan City; The spatial distribution of elderly care institutions at different levels presents different characteristics: large elderly care institutions are characterized by dual core agglomeration, while medium and small elderly care institutions are characterized by multi-core agglomeration; Spatial differentiation of elderly care institutions is caused by multiple factors, among which the number of elderly population has the greatest impact on the spatial distribution of elderly care institutions, while the vegetation coverage has the least obvious impact on the spatial distribution of elderly care institutions.
