Exploration of Chengdu’s Outdoor Spaces for Leisure and Fitness Based on POI Distribution Characteristics

以17305个高德地图提供的POI信息为研究对象,运用QGIS空间研究分析工具,分析成都市户外休闲健身空间的分布特征,探讨其与住宅区的关系.结果表明:1)成都市户外休闲健身空间整体呈现出“一心扩散,多点分散”的空间特征,核心点簇区其形状呈现出向南延展的特点;2)不同类别的户外休闲健身空间呈现出不同的分布特点;3)成都市的户外休闲健身空间与住宅区的关系整体上不完全符合我国15min生活圈规划的要求,郊县区域的居民其休闲健身需求以及积极性不能得到很好的满足.
