多视角下中原城市群高铁网络结构分析OA

This paper took the high-speed rail network in the Central Plains region as a case study,analyzing the network struc-ture of the Central Plains urban agglomeration from multiple perspectives,including network density and node centrality,network hierar-chical structure evolution,and the dynamic changes in the mean accessibility.The research findings were as follows:① With the in-crease in the number of connected entities significantly improved the strength of transportation links,driving the network density of the Central Plains urban agglomeration to shift from low to high.②Although the counties that historically held a strong position in tradition-al rail passenger transport maintained their status,the development of high-speed rail exacerbated the imbalance between counties.③Although the development of high-speed rail has reduced the overall degree of monopolarization in the flow-space network structure,this effect remains relatively limited.The spatial structure of the region still exhibited a tendency toward monopolarization,with Zheng-zhou playing a central role.④ Furthermore,the expansion of the high-speed rail network significantly enhanced the accessibility of counties within the Central Plains urban agglomeration.However,this improvement was constrained by geographic location and the con-ditions of high-speed rail infrastructure development.The enhancement of accessibility varied across cities,with Zhengzhou consistently maintaining a dominant position in terms of connectivity.
