| 摘 要： | 铁路客流是城市群内经济社会联系的重要反映,也是区域流空间的关键体现。本文依据流空间理论,采用复杂网络方法和2018年中国铁路班次OD数据,从全国尺度分析城市群社区结构特征,并从城市群尺度比较分析了5个主要城市群的空间结构、规模结构和网络节点结构。结果显示,从铁路客运班次联系来看,城市组团片区与国家规划方案中的城市群在范围上存在一定的空间错位。5个主要城市群具有不同的局部特征：① 长江三角洲城市群呈网络状的空间形态和相对集聚的规模分布,主要问题为局部节点的枢纽作用与规模的匹配性有待提高;② 珠江三角洲城市群呈放射状的空间形态和相对集聚的规模分布,主要问题为与全国其他城市群的联系相对薄弱;③ 京津冀城市群呈放射状的空间形态和相对集聚的规模分布,主要问题为存在边缘化的节点;④ 长江中游城市群呈组团状的空间形态和相对分散的规模分布,主要问题为内部结构较为松散;⑤ 成渝城市群呈哑铃状的空间形态和相对集聚的规模分布,主要问题为与全国其他城市群的联系薄弱。随着区域一体化进程,需要根据不同城市群网络结构发展阶段的差异,补足城市群内和城市群间的联系短板,促进规模位序结构与网络结构的耦合协调,推动建设层次分明、枢纽协作、网络化发展的客运服务网络,支撑城市群一体化发展。

| Abstract: | Railway passenger flows reflect economic and social interactions in urban agglomerations. Urban agglomeration is the basic regional unit for a country to participate in global competition and international division of labor. It is also the main form of China's new urbanization and an important carrier of modernization. The integrated development of urban agglomerations is one of the major strategies for the development of urban agglomerations in China. An important sign of urban agglomeration integration is the structural characteristics of population, goods, information, and other flows within the urban agglomeration. In this context, the theory of flow space is applied in this study. Based on China's railway schedule OD data in 2018, this study uses complex network approach to analyze the structure patterns of urban agglomerations at the national scale, and investigates the variations of the spatial structure, scale structure, and network node structure in the five major urban agglomerations. The results of analysis show that there is a certain spatial dislocation in the scope between the urban agglomeration area based on the railway schedule and the urban agglomeration in the planning scheme. The planning scope of urban agglomerations is often larger than that of railway passenger transport service supply network. This shows that the supply of railway passenger service may lag behind the urban agglomeration planning. The five major urban agglomerations, Yangtze River Delta, Pearl River Delta, Jingjinji, Middle reach of the Yangtze River, and Chengdu-Chongqing, have different local patterns. Yangtze River Delta has a network-shaped spatial form and centralized scale distribution, the main problem of which is the mismatch between hub function and scale of local nodes. Pearl River Delta has a radial spatial form and centralized scale distribution, the main problem of which is the relative weak connection with other urban agglomerations. Jingjinji has a radial spatial form and centralized scale distribution, the main problem of which is the existence of marginalized nodes. The middle reach of the Yangtze River has a cluster-like spatial form and decentralized scale distribution, the main problem of which is the loose internal structure. Chengdu-Chongqing has a dumbbell-shaped spatial form and centralized scale distribution, the main problem of which is the weak connection with other urban agglomerations. With the process of regional integration, it is necessary to make up for the weak links within and among urban agglomerations according to the differences in the development stages of the network structure, so as to promote the coordination with the scale structure. It is necessary to promote the construction of passenger transport service network with distinct levels, cooperative hubs, and balanced spatial form to support the integrated development of urban agglomeration. |
