高铁网络视角下中国城市体系空间结构审视

Reinvestigation of China’s Urban System from the Perspective of High-speed Rail Network

高铁网络是城市体系网络研究中的活跃分支。近年来随着高铁设施的快速发展,高铁带来的影响从区域层面上升到全国层面。在既有研究基础上,文章试图再次从高铁网络视角审视中国城市体系,在分析通行高铁城市、城市对的层级与格局的基础上增加类型分析,研究高铁影响下全国城市体系的层级与空间结构,探索其对新时代城市规划的启示,并得出了北京、上海、广州、深圳与成都是全国主要始末节点城市;高铁网络关联形成的相对区位优势使一些高铁城市进入更高层级;国家区域内初步形成了“网络—走廊—城市群”总体格局的结论。

High-speed rail network is a vibrant branch of the urban network researches.With the rapid development of national highspeed rail(HSR)system,the impact of HSR on the urban system has risen to the national level.On the basis of the existing research,this paper attempts to reinvestigate China's urban system from the perspective of HSR network.By analyzing the tiers and the spatial pattern of HSR cities and city-dyads and with the supplement of type analysis,this research attempts to look into the impacts of the HSR network on the hierarchy and spatial structure of the national urban system.The results show that Beijing,Shanghai,Guangzhou-Shenzhen and Chengdu are the main departure/destination node cities in national HSR network.The three major urban agglomerations,the provincial capitals in the central region and the central cities along the border region have been promoted by the network to enter the first and second tier through gaining stopover linkages.The overall pattern of"Network-Corridor-Urban Agglomeration"has initially formed in the national region.
