摘要/Abstract

摘要： 本文首先提出了探测城市网络中心性和对称性特征的方法框架,具体包括3个“S”的维度,即强度、对称性和结构。然后分别对京津冀、长三角和珠三角城市群的人流迁徙网络进行了实证分析。结果表明:①三大城市群内的城市节点具有明显的层级特征,且人流迁徙呈现较大的对称性结构;②京津冀、长三角和珠三角分别呈现包围式、“>”形及“一核两翼”的核心-边缘结构;③京津冀呈典型的单中心结构,而长三角和珠三角则呈明显的多中心结构。最后结合上述分析结果,对于三大城市群的城市定位、区域规划给出了建议,旨在促进区域的协调发展和一体化集成。

Abstract: Focusing on the analysis of the centrality and symmetry patterns of the nodes and links on urban network, this study proposes a method framework which includes three “S” dimensions.It is strength, symmetry, and structure, respectively. Further, the above framework is applied to the migration network of Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (YRD), and Pearl River Delta (PRD) urban agglomerations, and the following findings can be obtained: ① The urban nodes and the migration of people in the three major urban agglomerations have obvious hierarchical and symmetrical structures, respectively. ② The BTH, YRD, and PRD respectively presents a core-periphery structure with a surrounding, “>” shape, and one core and two wings. ③ The BTH presents a typical single-center structure, while the YRD and the PRD present obvious multi-center structure. The above findings can be helped to make suggestions for the urban positioning and regional planning of the three urban agglomerations, which can promote the coordinated development and integration of those regions.
