基于复杂网络的成渝地区双城经济圈区域铁路网络时空演化研究
Spatial and Temporal Evolution of Regional Railway Network in Chengdu-Chongqing Economic Circle Based on Complex Network
摘要
Abstract
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.关键词
