How to qualitatively and quantitatively evaluate the ability of the whole subway system to maintain the maximum normal operation has become a noteworthy topic. In this study, the hypergraph space structure of Nanjing subway network is used for research. This study uses the method of time-space evolution mechanism to dynamically and quantitatively analyze the gradual change characteristics of Nanjing subway system vulnerability under the influence of time and space. In addition, this study also makes static and dynamic comparative analysis on the vulnerability of a subway system by using connectivity rate and trip efficiency index, which provides new analysis methods and ideas for the study of a subway system network. The results show that although the overall structure of Nanjing’s subway network shows a loose trend, as Nanjing’s subway is still in a rapid development stage, it can be seen from the long-term planning of Nanjing’s subway that the construction of Nanjing’s subway ring line will be strengthened after the completion of the connection between the main city and the suburbs. Therefore, the vulnerability of the subway system should be reduced and the reliability will be improved.

基于超图空间的地铁脆弱性时空演化

如何定性和定量地评估整个地铁系统维持最大正常运行的能力已成为一个值得注意的话题。本研究以南京地铁网的超图空间结构为研究对象。本研究采用时空演化机制的方法，动态定量地分析了南京地铁系统在时空影响下的脆弱性逐步变化特征。此外，本研究还利用连通率和出行效率指标对地铁系统的脆弱性进行了静态和动态的比较分析，为地铁系统网络的研究提供了新的分析方法和思路。结果表明，尽管南京地铁网络的总体结构呈现出宽松的趋势，由于南京地铁仍处于快速发展阶段，从南京地铁的长远规划可以看出，南京地铁环线的建设将在主城区与郊区连接完成后得到加强。因此，应该减少地铁系统的脆弱性并提高可靠性。
