摘　　要：【目的】认识都市圈空间组织形式是推动都市圈发展、制定空间规划策略的基础性议题。本文从人员要素流动的跨城功能性联系入手认识都市圈空间组织形式,探究其形成机制。【方法】以人员要素流动的跨城功能性联系体现的“流动空间”理论为基础,构建了都市圈空间组织形式及形成机制的理论分析框架。以上海都市圈为案例,使用2023年时空大数据和出行等时圈分析人员要素流动承载的跨城功能性联系的目的地空间特征、时间特征,得出都市圈空间组织形式及其形成机制。【结果】(1)都市圈是由跨城功能性联系连接的功能性地域概念,跨城功能性联系主导了都市圈空间组织形式。(2)人员要素流动承载的跨城功能性联系在空间上与核心城市特有城市功能关联,在时间上的强约束性需要城际快速交通体系支撑。(3)在人员要素流动的跨城功能性联系主导下,都市圈在空间组织形式上呈现为“圈层+链状”,在机制上是由城际快速交通体系的“时空压缩”和“时空管道”效应、跨城功能性联系时空特征两者共同作用形成。【结论】跨城功能性联系体现的“流动空间”重塑了都市圈空间组织,进而形成了都市圈“圈层+链状”的空间组织形式。优化都市圈空间规划策略需构建支撑跨城功能性联系的都市圈“流动空间”体系。[Objective]Understanding the spatial organization forms of metropolitan regions is fundamental for promoting their development and formulating spatial planning strategies.This study aimed to shed light on the spatial organization forms of metropolitan regions and explore the underlay mechanism by focusing on intercity functional linkages of human element flows.[Methods]Based on the“space of flow”represented by intercity functional linkages of human element flows,a theoretical framework of analysis was developed to analyze the spatial organization forms of metropolitan regions and mechanism.Using the Shanghai Metropolitan Region as a case study,this study employed spatiotemporal big data and traffic isochrons to identify the spatial and temporal characteristics associated with the destinations of intercity functional linkages driven by human element flows.[Results](1)Metropolitan regions are functional regions shaped by the intercity functional linkages.These linkages dominate the spatial organization of metropolitan regions.(2)The intercity functional linkages of human element flows are spatially associated with the unique urban functions of core cities,while its temporal constraints require support from intercity rapid transportation systems.(3)Under the dominance of intercity functional linkages,the spatial organization of metropolitan regions manifests as“circles+chains”,resulting from the spatial-temporal compression and pipeline effects of the rapid transportation system,as well as the spatiotemporal characteristics of intercity functional linkages.[Conclusion]The“circles+chains”spatial organization form emerged from the reshaping of metropolitan region spatial organization by the“space of flow”represented by intercity functional linkages.Therefore,the spatial planning strategies of the metropolitan region should construct a system of the“space of flow”for supporting intercity functional linkages.
