Abstract
Based on the POI data of six types of public facilities in Quanzhou,spatial distribution was assessed by using kernel density analysis,standard deviation ellipse analysis,correlation analysis,and the CRITIC method.The research findings indicate that:(1)Public facilities in Quanzhou are clustered,with a well-developed infrastructure in the Huanyuan urban area at the intersection of Licheng District,Fengze District,and Jinjiang City.Elderly care services and cultural sports facilities are sparsely distributed,with low spatial concentration,indicating a need for improved development in these areas.(2)Public service facilities are centered around the Huanwan Urban Area,decreasing towards the urban fringe,with significant differences in the distribution of various types of facilities.(3)The layout of the six types of facilities follows a northwest-southeast orientation,with educational facilities having the broadest coverage and most pronounced direction.(4)Commercial service facilities have the strongest correlation with healthcare facilities,likely because they both cater to fundamental needs and developmental enhancement,thus serving a wider audience.(5)The distribution of public service facilities is optimal in Fengze Street of Fengze District,Huguang Road in Qingyang Street of Jinjiang City,and Hubin Street of Shishi City,with facility completeness gradually decreasing in surrounding areas.The research results provide valuable guidance for the rational allocation of public service facilities in Quanzhou City.关键词
