摘　　要：以轨道交通发展较为成熟的北京和上海为对象,以复杂网络理论为基础,在GIS支持下构建了反映轨道交通网络基本特征、空间分布特征、网络结构特征的系列指标,对两地轨道交通进行对比分析。主要结论为:两地的轨道交通基本特征相似;两地轨道交通在距市中心15km范围内较为发达,上海在城市中心范围的便利性更优;北京轨道交通网络在城区外围能更方便地实现换乘,上海则与之相反。研究结果可为其他城市轨道交通系统规划与建设提供参考。Taking Beijing and Shanghai with more developed rail transit system as objects and based on the theory of complex networks, the paper firstly constructed a series of indicators to describe the basic characteristics, spatial distribution characteristics and network structure characteristics of rail transit system. Then, in support of geographic information system, the characteristics of rail transit system in Beijing and Shanghai were analyzed comparatively. The main conclusions are as follows. The rail transit in Beijing and Shanghai are similar in station numbers, total length of lines and transfer station numbers. However, there is a slight difference in terms of average distance between stations. Moreover, the rail transits in both cities are densely distributed within the range of 15kin from downtown, which means a high convenience in this area, and the rail transit in downtown of Shanghai is more convenient than that in downtown of Beijing. Finally, the rail transit network in the region of Beijing far from downtown can be more easily achieved with transfer between lines, but the rail transit network in Shanghai has transfer advantage in the downtown area. The research results would provide a reference for the planning and construction of rail transit system in other cities.
