时空行为视角下多层级城市生活圈空间结构测度与类型划分研究——以北京市为例
Spatial Structure Measurement and Classification of Multi-level Urban Life Circle from the Perspective of Space Time Behavior Analysis:A Case Study of Beijing
摘要
Abstract
Utilizing spatiotemporal big data,this study conducts empirical research on multi-level urban life circles in Beijing from the perspective of the urban life circle theory.Combining quantitative methods such as community detection,kernel density estimation,and multi-algorithm clustering,boundaries of community life circles,commuting life circles,and extended life circles in Beijing are analyzed respectively.A"community-stay point-path"network generated from residents'activities is mapped,which reveals spatiotemporal patterns of various daily travels of community life circles.Applying the K-Medoids clustering algorithm on Hausdorffdistance between travel distance-probability curves of commuting and non-work trips separately,community life circles are classified into several distinct categories,upon which in-depth case studies are carried out.Results demonstrate that Beijing's life circles have five patterns:balanced,commute-dependent,life-dependent,corridor-oriented,and special pattern.Differences primarily exist in the spatial relativity of employment and activity life circles to places of residence and urban centers,showing significant concentric and polycentric spatial distribution.The study not only provides empirical insights into the spatial logic of urban life circles but also offers data-driven references for urban planning and governance practices.关键词
