摘要
基于网络分析OD成本矩阵,运用引力模型获得2009年和2022年中原城市群30个城市经济数据,利用社会网络分析法探究高铁对中原城市群网络空间结构的影响.研究发现:(1)伴随高铁线网的不断延伸和加密,中原城市群城市程度中心度呈现上升趋势,城市间组团发展模式更加显著,网络的核心地区由中部向西部呈动态扩展的变化趋势.中介中心度呈现下降态势,其空间分布特征显著,中介城市从郑州和菏泽逐渐向徐兰高铁线的郑州、开封、洛阳和商丘迁移,区域内个体城市中介能力呈现均衡发展态势.(2)高铁建设提升城市网络整体密度,但仍处于弱连接状态.核心-边缘结构逐渐弱化,核心区范围扩大,边缘区范围减小.随着高铁网络推进,凝聚子群结构发生剧烈变化,石武高铁轴线子群成为中原城市群经济联系的核心组团.
Using the data of economic connection strength in three scenarios without high-speed rail(HSR),2017and 2025 HSR networks,and using spatial interaction and complex network research methods,from the perspective of the overall network structure and node structure,the impact of HSR construction on the urban network spatial structure of the Central Plains urban agglomeration(CPUA)was analyzed.From the point of view of network node structure,the degree of centrality of the city shows an upward trend,the development model of inter-city grouping is more significant,and the dynamic change trend of the core area of the network is observed from the center to the west.The centrality of intermediaries is declining,and its spatial distribution is remarkable.Intermediary cities have gradually moved from Zhengzhou and Heze to Zhengzhou,Kaifeng,Luoyang,and Shangqiu of the Xulan HSR Line.The overall density of the urban network has increased significantly,but it is still in a weakly connected state.The core-edge structure gradually weakened,the core area expanded,and the edge area decreased.With the advancement of the HSR network,the structure of regional cohesion subgroups has undergone dramatic changes,and the Shiwu HSR axis subgroups have become the core group of economic links in the CPUA.
