摘　　要：城市的公共服务设施是一个城市提供服务能力的重要体现。本文以广州市为例,利用高德地图采集的公共服务设施POI数据,通过核密度分析、方向分布分析、相关性分析以及综合配置水平评价等空间分析方法,探究研究区公共服务设施的空间布局。得出结果如下:第一、广州市公共服务设施分布不均衡,市中心聚集性明显,总体呈现单中心或多种的模式存在。第二、各类设施间分布方向基本一致,往南北方向发展。第三、设施间相关性较强,城市发展功能分区明显,职住分离。第四、公共服务设施综合配置水平较高,区域差异明显,医疗卫生设施综合水平较低。本文的研究结果,可为广州市公共服务设施的规划提供决策参考,为POI数据在城市规划中的应用做进一步的探索。The public service facilities in a city are an important embodiment of a city's ability to provide services.Taking Guangzhou as an example,this paper uses POI data of public service facilities collected by Gaode map to explore the spatial layout of public service facilities in the research area through spatial analysis methods such as kernel density analysis,direction distribution analysis,correlation analysis and comprehensive configuration level evaluation.The results are as follows:first,the distribution of public service facilities in Guangzhou is not balanced,the city center is obviously clustered,and there are generally single center or multiple models.Second,the distribution of all kinds of facilities is basically the same,developing in the north-south direction.Thirdly,the correlation between facilities is strong.The functional zoning of urban development is obvious.Fourth,the comprehensive allocation level of public service facilities is relatively high,with obvious regional differences,and the comprehensive level of medical and health facilities is relatively low.The research results of this paper can provide decision-making reference for the planning of public service facilities in Guangzhou and further explore the application of POI data in urban planning.
