客运铁路视角下长江中游城市群网络结构研究
|
摘要
铁路运输是城市间的重要联系方式,能够较好的反映出城市网络结构。从12306购票网络获取了铁路客运数据,以列车数量和运行速度进行加权来构建无向加权矩阵,从城市节点和城市间联系两个角度研究长江中游城市群网络结构。研究发现,长江中游城市群呈现出以长沙、武汉、南昌为核心城市的多中心发展格局,顶层联系网络将核心城市联系在一起,不同区域的发展模式不同。火车流量有向顶层节点、顶层联系集中的特点。
Railway transportation is an important way of connecting cities in different regions,which can reflect the characteristics of the urban network.This paper obtains the passenger data of the railway from 12306 China Railway, weights the inter-city linkages by the number of trains and the running speed to construct an undirected weighting matrix, and studies the urban network structure in urban agglomeration in the middle reaches of the Yangtze River(UAMRYR) from the perspective of urban nodes and inter-city linkages.The study finds that: UAMRYR presents a multi-center development pattern with Changsha, Wuhan and Nanchang as the core cities; Top-level contact network links core cities; Different regions have different development models; the train traffic has the characteristics of being connected to the top node and the top layer.
