职住双重锚点:中心城区社区公共绿地服务范围的解析——以上海市黄浦区为例

Residence and Workplace as Dual Anchors:Analyzing Service Radius of Community-level Green Space in Central Urban Area:A Case Study of Huangpu District,Shanghai

社区公共绿地是社区层级的重要公共基础设施,准确理解其服务范围对规划治理具有现实意义。针对中心城区社区公共绿地的超距离服务现象和就业人口的双生活圈设施使用现象,提出职住双锚点假设。以上海市黄浦区为案例,探索双锚点下访问距离的可解释性、访问时间的聚集表现和居住地的空间分布,并讨论超距离服务范围的影响因素。结果显示,相比传统单居住锚点,职住双锚点分析模式增强了中心城区社区公共绿地服务范围的解释性,中心城区绿地服务范围受职住距离影响,且职住锚点具有不同的访问高峰时段。中心城区社区公共绿地的超远服务距离构成职住分离的侧写,在公共绿地的治理规划工作中应当考虑职住活动的影响。

Community green spaces are essential public infrastructure at the community level,and understanding their service range is crucial for planning and governance.This study addresses the phenomenon of overextended service ranges of community green spaces in central urban areas and the dual life circle facility usage of employed populations,proposing the dual-anchor hypothe-sis of residential and workplace locations.Using community green spaces in Huangpu District,Shanghai,as a case study,the re-search explores the explanatory power of visit distances under dual anchors,the clustering patterns of visit times,and the spatial distribution of residences.The study also examines the factors infl uencing overextended service ranges.The fi ndings indicate that the dual-anchors analysis model,focusing on both employment and living,compared to the traditional single-living-anchor model,enhances the explanation of the service range of community-level public green spaces in the central urban area,and the service range is infl uenced by the distance between employment and living spaces,the two types of anchors exhibit different peak access times.The extended service distance of community-level public green spaces in the central urban area constitutes a profi le of job-residence separation,and the impact of job and residence activities should be considered in the governance and planning of public green spaces.
