Study on the spatial distribution characteristics and accessibility of elderly care facilities in Yiyang City
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.
