摘　　要：基于复杂网络理论,借助Space L空间方法,构建区域铁路网络拓扑结构模型,研究2000—2030年成渝地区双城经济圈区域铁路网络时空演化。将成渝区域铁路网络的演化划分为初步发展、快速发展、高等化完善化3个发展阶段,分析铁路网络整体结构特征与节点特征的演化,结果表明,成渝地区双城经济圈区域铁路网络空间格局分布存在差异性,成渝地区双城经济圈内部已演变形成以成都、重庆双核心为引领,以遂宁、南充、合川等城市为次核心的非均衡区域铁路网络;随着铁路站点与线路的增加,成渝地区双城经济圈区域铁路网络逐渐呈现小世界特性,核心-边缘的分异特征较为明显;第二阶段的网络化水平提升幅度高于第一阶段的网络化水平提升幅度,且区域边缘节点城市的中心性指标提升较大。Based on complex network theory and the Space L space method,this paper constructed a topological structure model of the regional railway network to study the spatial and temporal evolution of the regional railway network in Chengdu-Chongqing Economic Circle from 2000 to 2030.The paper divided the evolution of the Chengdu Chongqing regional railway network into three development stages:preliminary development,rapid development,and advanced and improved development,and analyzed the overall structural characteristics and node characteristics of the railway network.The results show that the spatial pattern distribution of Chengdu-Chongqing Economic Circle regional railway network is significantly different,and an unbalanced regional railway network with Chengdu and Chongqing as the core and Suining,Nanchong,Hechuan and other cities as the sub-core,has evolved within the Chengdu-Chongqing Economic Circle.With the increase in railway stations and lines,the regional railway network of Chengdu-Chongqing Economic Circle gradually presents the small world characteristics,and the core edge differentiation is more obvious.The level of networking in the second stage is higher than in the first stage,and the centrality index of the regional edge node cities is greatly improved.
