文章采用网络爬虫技术获取了2021年湖南省14个市(州)养老设施的POI样本点数据,并基于ArcGIS进行坐标和投影转换,实现数据的可视化表达.进一步运用最邻近分析和核密度分析,探讨湖南省养老设施的空间分布特征,并依据一致性系数计算公式,探究湖南省14个市(州)养老资源的集聚程度,最后运用地理探测器方法探测湖南省各市(州)养老设施的空间分异成因.研究发现:①湖南省养老设施整体最邻近指数约为0.613,呈现显著集聚的分布状态,分布密度总体上"东密西疏、北密南疏".②湖南省各市(州)的养老资源一致性在地域上分异明显,养老资源投入与老年人口分布表现出弱协调性.③地理探测器的因子探测结果显示,老年人口数量、经济发展水平、医疗保健设施数是影响各市(州)养老设施数量分布的主要因素,其中老年人口数是最直接的原因,直接决定着养老设施的建设问题.④地理探测器的交互探测结果表明,养老设施的分布受多个因子的共同作用,老年人口数量与其他因子叠加后能够对养老设施的空间分异产生更强的解释力.
Spatial Distribution Characteristics of Facilities for the Elders in Hunan Province and Its Causes Based on the POI Data
This study uses the web crawler technology to obtain the POI data of facilities for the elders in prefecture-level cities of Hunan Province in 2021,and carries out the coordinate and projection transformation based on ArcGIS to realize data visualization.Based on the above,it uses the nearest neighbor analysis and kernel density analysis to explore the spatial distribution characteristics of facilities for the elders in Hunan Province.According to the consistency coefficient calculation formula and the geographic detector,it explores the concentration degree of facilities for the elders and detects the cause of spatial differentiation of facilities for the elders in prefecture-level cities of Hunan Province.It's found that:1)The overall nearest neighbor index of facilities for the elders is 0.613 in Hunan Province,showing a significantly agglomeration distribution,and the distribution density is generally"dense in the east of Hunan Province and sparse in the west of Hunan Province,dense in the north of Hunan Province and sparse in the south of Hunan Province".2)The consistency of facilities for the elders is obviously different in prefecture-level cities of Hunan Province,and the investment of facilities for the elders and the distribution of the elderly population show weak coordination.3)The factor detection results of the geographic detector show that the number of elderly population,the level of urban economic development and number of healthcare facilities are the main factors affecting the number of facilities for the elders,the number of elderly population is the most essential reason,directly determining the construction of facilities for the elders.4)The interactive detection results of geographic detector show that the distribution of facilities for the elders is affected by multiple factors,and the superposition of the number of elderly population and other factors can produce a stronger explanation for the spatial differentiation of facilities for the elders.
