摘要:

高速铁路作为现代交通基础设施的重要组成部分,其建设产生时空收敛效果,并进一步对生产要素流动、城市空间扩张、区域空间结构重构产生重要影响。文章在分析中国高速铁路发展过程、模式的基础上,剖析了其空间格局特征及与区域人口和经济的耦合关系;同时,借助ArcGIS方法从空间服务水平、时空收敛效应和中心城市交通圈等角度,探讨高速铁路网络的空间效应。结果显示:高速铁路的空间扩展过程表现出独特的“核心―核心”至“核心―网络”模式,与城市群的空间分布具有较好的耦合性;高速铁路的空间格局与中国城市人口、工业分布表现基本一致,站点1 h范围内可覆盖全国50.07%的城镇人口、73.47%的GDP和98.17%的第二产业产值;中国高速铁路建设导致的时空收敛效果呈现出明显的廊道效应,中心城市枢纽地位得以强化,服务范围的拓展和生产要素的便捷流动为城市群的空间扩张和重构提供了条件。

Abstract:

High speed rail (HSR) is an important part of modern transport infrastructure. The construction of HSR network induces the spatio-temporal convergence and further influences the movement of production elements, the expansion of urban areas as well as the reorganization of regional spatial structure. The paper first analyzes the development process and mode of China’s HSR network, and then explores the characteristics of spatial distribution pattern as well as the coupling relationship with population and economy. Finally, the paper researches the spatial effects of HSR network with GIS method, in terms of the service areas of HSR, time-space convergence effects, and core cities’ commuting regions. Results indicate that: 1)The spatial expansion of HSR in China shows a “core-core” pattern in the early years and then a “core-network” pattern, which is closely related with the distribution of cluster cities; 2) The spatial pattern of HSR is inclined to serve the urban population and industry output, with 50.07% urban population, 73.47% GDP and 98.17% industry output value in 1 hour catchment area; 3) The HSR network leads to an uneven time-space convergence, and cities along the main HSR lines have relatively lower average travel time, showing a corridor effect; Meanwhile, the accessibility of hub cities are improved greatly, which leads to the expansion of hinterlands and convenient movement of production elements as well as the integration of cities in megalopolis.
