摘要
为从全时、全域、全设施角度构建公平、精细的休闲生活圈体系,文章以上海市嘉定新城为例,在休闲需求理论、时间地理学的指导下,基于休闲时间可用性和休闲设施可达性之间的匹配度,以时间、空间、设施和地方性4个规划要素构建日常、扩展、机会3级圈层体系,并利用POI数据和网络分析法刻画各级各类休闲设施的服务范围以分析其使用的可达性和便利度。结果表明,路网密度、交通供给、设施布局影响休闲设施可达性、休闲出行便利度以及休闲供给公平性,进而造成休闲服务水平差异。据此,从交通路网优化、设施配置调整、功能节点联动等方面提出优化策略,以期为城市公共休闲服务基础设施体系建设提供参考。
In order to build a fair and sophisticated system of leisure life circle from the full-time,whole-area and all-facility perspectives,this paper takes Jiading New Town in Shanghai as a case and adopts the leisure demand theory and time geography,to outline a 3-level leisure life circle including daily,expansional and casual circles with 4 planning elements of time,space,facility and endemicity,based on the matching degree between the availability of leisure time and the accessibility of leisure facility.POI data and network analysis are then used to define the service areas of the facilities at all hierarchies for demonstrating their accessibility and convenience.The results show that road density,traffic supply and facility layout affect the accessibility of leisure facilities,the convenience of leisure travel,and the fairness of leisure supply,which are the factors to the differences in leisure services.In this sense,optimization strategies are proposed in terms of traffic road network optimization,facility configuration adjustment and functional node linkage,so as to provide a reference for public leisure infrastructure construction in cities.
