摘　　要：中心区圈核结构模式是指在城市中心地区中,由公共设施主核与亚核体系及其扩散圈层、轴环连线所组成的一种空间集聚结构现象,它广泛存在于我国特大城市中心地区。文章在研究国内典型中心区的基础上,从形成机理方面剖析其源于城市服务业的聚集效应与分离效应的空间叠合,提出由于圈核结构模式兼顾了城市中心的趋中性和特色功能的边缘性,从可以实现多核中心区在内部区位上和功能上的互补,进而提出圈核结构中心区发展的空间规律。The circle-core structure mode refers to the phenomenon of a spatial concentration structure that widely exists in urban central districts of Chinese megacities. It consists of the main and sub cores of public facilities, their diffusion areas,and the connections among them. Based on the research of typical urban central districts in China,this article analyzes the formation mechanism of the circle-core structure mode, suggesting that it originated from the spatial superimposition of the concentration and separation effects of urban service industry. Since the circle-core structure mode takes into account both the centrality of urban centers and peripherality of featured functions, it could promote the spatial and functional inter-complementation among multiple cores of the urban central districts. Based on these analyses, this article proposed the spatial regularity of the circle-core structure mode.
