| 摘 要： | 本文以中原城市群为研究区，构建了新闻中地名共现网络，并搭建了探测城市网络社区结构和核心-边缘结构的方法框架。结果表明：①中原城市群被划分为5个社区，省级界线在虚拟网络空间城市的交互中起到了较大的阻碍作用；②在河南省城市所组成的核心-边缘结构中，核心城市围绕郑州呈斜"L"形分布；③中原城市群内郑州的中心地位较突出，洛阳的副中心地位不明显，整体多中心水平较低。基于以上结果，本文从区域规划、城市角色定位等方面给出了建议，对于中原城市群的一体化集成与发展有一定的促进作用。

| Abstract: | In this study, the central plains urban agglomeration (CPUA) is selected as the study area to construct a city network using toponym co-occurrence in the news. Furthermore, a method framework is proposed to detect community structure and core-peripheral structure of the resultant network. The following findings are obtained:① The CPUA are divided into 5 communities and the provincial boundary has played a major role in hindering the interaction between cities in virtual cyberspace. ② In the core-periphery structure composed of cities in Henan province, the identified core cities are distributed in an oblique "L" shape around Zhengzhou.③The central position of Zhengzhou is more prominent, while Luoyang's sub-center status is not obvious, and the overall multi-center level of CPUA is relatively low. Based on the above findings, suggestions are given from regional planning and urban role positioning for the integration of cities within the CPUA. |
