城市-区域视角下的粤港澳大湾区都市圈空间组织模式

Spatial Patterns of Metropolitan Areas in the Guangdong-Hong Kong-Macao Greater Bay Area from City-region Viewpoint

近年来,都市圈逐渐成为中国城镇化的重要空间单元,其空间结构和组织方式对规划实践与政策制定具有重要作用。文章在比较全球都市圈空间结构案例与回顾粤港澳大湾区都市圈发展历程的基础上,基于城市—区域视角,采用人口流动数据表征都市圈内大中小城市空间集聚的结构关系,对珠三角内各都市圈空间结构的现状进行测度,得出广州都市圈是纵向扩展的强核心簇群结构、深圳都市圈是横向扩展的多中心分布结构、珠江口西岸都市圈则是形成中的多中心环布式结构等,并分析了3种不同空间结构的形成机制,进而提出对应的规划策略。

Metropolitan area has become an important spatial unit in China’s urbanization,and its spatial structure and organization is important to the planning practice and policy formulation.The paper compares several global metropolitan areas,reviews the evolution of metropolitan areas within the Guangdong-Hong Kong-Macao Greater Bay Area,studies the spatial agglomeration structure of large,middle,and small cities based on transient population network,and measures the spatial structure of metropolitan areas in the Pearl River Delta region.It concludes that Guangzhou metropolitan area is a“scale up”structure with a strong core expanding vertically;Shenzhen metropolitan area is a“scale out”structure with a multi-center structure expanding horizontally.Zhuhai-Zhongshan-Jiangmen metropolitan area is a ring structure with multiple centers in formation.The three spatial structures area further analyzed and correspondent planning strategies are proposed.
