伴随全球化、信息化的深入，城市外部关系理论逐渐由中心地理论转向了流空间理论。文章基于层级性空间与流动性空间("层级—流")自身作用规律，从形态、功能、尺度3个维度构建了"层级—流"结合作用下的现代都市圈空间演化分析框架，提出了"层级—流"共同作用于中国现代都市圈空间的演化特征和机理。研究发现:①基于规模、功能、行政层级的层级性空间作用机制主要是层级集聚、功能覆盖、权力控制，基于多维要素流的流动性空间的作用机制包括分工合作、规模借用、负向反馈。"层级—流"交互促进了都市圈尺度的空间整合与重构。②城镇层级会影响要素流集聚—扩散的规模与方向并进而影响都市圈网络的建构;要素流动则通过资源的空间再布局重塑了都市圈的层级体系与功能结构。③武汉都市圈案例证实了"层级—流"在现代都市圈空间演化中的耦合作用，两者促进了武汉都市圈形态多中心网络化、生产功能多尺度网络耦合、生活功能协调化、生态空间共建共治以及空间关系的尺度重构。
Spatial Evolution Mechanism of Modern Metropolitan Areas under the Combined Effect of Hierarchy-flow:A Case Study of Wuhan Metropolitan Area
With the advancement of globalization and informatization,the theory of urban external relations has gradually shifted from the central place theory to the flowing space theory.However,the construction of China's modern metropolitan areas(MMAs)faces a parallel background of globalization,informatization,industrialization and urbanization.This paper proposes that space hierarchies and flows(hierarchy-flow)have a combined effect on the spatial evolution of China's MMAs.Based on the function law of"hierarchy-flow",this paper constructs the spatial evolution analysis framework of MMAs under the combination of"hierarchy-flow"from three dimensions:spatial morphology,function and scale.The research points out that:1)The mechanism of hierarchical space based on scale,functional and administrative hierarchy is mainly hierarchical agglomeration,functional coverage and power control.Meanwhile,the mechanism of flowing space based on multidimensional factor flows includes division of labor,cooperation,size borrowing and bottom-up feedback.The interaction of"hierarchy-flow"promotes the spatial integration and reconstruction of metropolitan scale.2)Urban hierarchy affects the scale and direction of factor flows,which in turn affects the construction of the metropolitan network.Factor flows reshape the hierarchy and functional structure of the metropolitan area through the spatial redistribution of resources.3)The case of Wuhan metropolitan area confirms coupling effects of"hierarchy-flow"in the spatial evolution of MMAs.Both promote the polycentric networking of spatial forms,the multi-scale network coupling of production functions,the harmonization of living functions,the co-construction and co-governance of ecological space,and the scale reconstruction of spatial relations in the Wuhan metropolitan area.The study facilitates the understanding of the mechanism of spatial evolution in MMAs,and also provides insights into the sustainable development and collaborative governance of MMAs.
