【摘要】 作为城市公共建设程度和发展程度衡量指标之一的公共设施空间分布结构，其现状特征的研究关系着城市资源利用的持续性和合理性规划。本文以汕头市为例，以2019年百度地图公共设施兴趣点(POI)为研究对象，统计汕头市各行政区内公共设施空间分布的数量差异，通过平均最近邻分析法、核密度分析法和热点分析法实现对汕头市公共设施的空间集聚特征进行分析，并通过缓冲分析计算各公共设施的覆盖率。得出以下结论：医疗保健类、文体科技类、集贸市场类、行政管理类、商业金融类、教育机构类，其集聚程度依次增强；公共设施总体分布各异，主要表现为空间上的不均衡，在各区县中心都呈现出不同程度的集聚现象。更多还原

【Abstract】 The spatial distribution structure of public facilities as an indicator of the degree of public construction and development of the city, the current state of the urban landscape and its characteristics. The research is related to the sustainability and rational planning of urban resource use. In this paper, we take Shantou City as an example and take the 2019 Baidu Map Public Facilities Points of Interest(POI) as the research object, statistics quantitative differences in the spatial distribution of public facilities in Shantou City by means of mean nearest neighbor analysis, kernel density analysis and hotspot analysis. Spatial clustering characteristics of public facilities in Shantou are analyzed by the analysis method and the coverage of each facility is calculated by buffer analysis.. The following conclusions were drawn: health care, culture, sports and technology, markets, administration, business and finance, educational institutions. The concentration of public facilities has increased in descending order; the overall distribution of public facilities varies, mainly in terms of spatial imbalance, with a high degree of concentration in all district and county centres. Various levels of clustering were observed.更多还原
