客运通道是国家经济社会发展的重要物质基础，在综合运输体系中占有重要地位. 本文从客运通道的拓扑结构和空间形态分布两个角度分析了珠三角客运通道的结构特征，并提出了现状问题. 研究表明：珠三角客运通道的各种运输方式中铁路的运输效率最高，公路的鲁棒性最好；客运通道的演化是短期和长期生存效用共同作用的结果. 珠三角客运通道具备分形特征，公路的网络覆盖度最大为1.495，铁路最小为1.050. 指出铁路发展相对滞后，在规划轨道网络建设完成后，网络连通性将增大3倍，各个城市之间的联系也将更加紧密，轨道交通网络的标准熵将增加4.48%，轨道交通网络覆盖度将增大36.19%，客运通道结构将得到改善.

Structural Analysis of Pearl River Delta Passenger Transport Corridors

Passenger transport corridor connects major cities and transport hubs,which is the material base of social and economic development.Based on topological structure and space form features of integrated transport network,this paper focuses on structure development of Pearl River Delta passenger transport corridors.The research reveals that railway is the most efficient mode,and road transport possesses the best robustness.The changing of passenger transport corridors results from the interaction between short...
