【摘要】 分析城市POI数据与道路网络接近中心性的空间耦合关系，对于探究POI空间分布规律、引导城市各功能区合理布局具有重要意义。以石家庄中心城区为研究范围，依托Arc GIS平台分析了各类POI数据的空间分布特征，运用城市网络分析对道路网络的接近中心性进行测度。通过双因素组合制图对二者的空间耦合关系进行可视化分析，揭示了不同密度、不同类型的POI空间分布规律。更多还原

【Abstract】 Analyzing the spatial coupling relationship between urban POI data and the closeness of road network is of great significance to explore the spatial distribution law of POI and guide the rational layout of urban functional areas. Taking the central urban area of Shijiazhuang as the study area, this paper analyzes the spatial distribution characteristics of POI data through Arc GIS, and measures the closeness of road network by using urban network analysis. Finally, this paper visually analyzes the spatial coupling relationship between the urban POI data and the closeness of road network through two factor combination mapping, and reveals the spatial distribution law of POI with different density and different types.更多还原
