基于陆路客运联系的川渝城市客运网络联系格局

Network Contact Pattern in Sichuan-Chongqing Urban Based on Land Passenger Linkage

随着区域间联系的空间障碍不断被新的交通、通讯技术手段克服,各种流在城市与区域空间高速流动,形成了紧密的关联网络,流空间应运而生。其中,客流凭借其良好的表征能力成为刻画区域网络格局的常用手段。运用社会网络分析方法,采用中心性、核心边缘结构、不对称性等指标对川渝城市群陆路客运流进行了分析。研究表明:(1)川渝陆路客流网络总体呈现出显著的"T"字型结构;(2)重庆市陆运客流网络的辐射范围与其行政区划范围不一致;(3)泸州市未来在成渝合作中的地位不容小觑;(4)铁路客流网络发育与公路客流网络相比欠发达;(5)公路客流网络与工业经济发展程度密切相关,铁路客流网络与经济总量相关性较强。

With the spacial obstacle for regional communication constantly be overcomed by new traffic and telecommunication technology, various flows flowed in high speed between urban and regional space, where close relation network forms and the space of flows emerged.Among these flows, passenger flow became the most common means for describing spatial network pattern, because it enjoyed a good representation ability. This paper analyzed the Sichuan - Chongqing land passenger flow by using social network analysis and adopting some indexes such as centrality,core- periphery structure and asymmetry. The results showed that：（1）The land passenger flow network in Sichuan - Chongqing presented a ＂T＂ structure apparently. （2）The radiation range of Chongqing land passenger network was inconsistent with its administrative division. （3）The role of Luzhou cannot be neglected during the cooperation of Sichuan and Chongqing in the futm＇e. （4）The development of the highway passenger flow network was more superior than that of railway. （5）The highway passenger flow network was closely related to the development of industrial economy, but there existed a strong correlation between the railway passenger flow network and economic aggregate.
