摘要
为了研究中国高铁网节点中心性及其进化情况,针对中国高铁2017年底、2020年初的分布情况及国家高铁网八纵八横规划(2035年)分别构建了基于图论的中国高铁网.通过对交通网节点中心性评估算法的分析,提出了中国高铁网重要节点的评估方法.通过仿真实验分析了不同参数组合得到的结果,并据此分别确定了不同时段(2017、2020、2035)的重要节点Top20,对这些节点中心性的进化过程进行对比,分析了部分重要节点排名波动的原因.
In order to study the nodes importance and its evolution of the high-speed rail network of China,the network based on graph theory that focused on the actually situation of China high-speed rail network in the year of 2017,2020 and the national high-speed rail network plan with eight vertical and eight horizontal line(2035)were constructed,respectively.Based on the analysis of the evaluation algorithms for nodes importance of transport network,the evaluation method on the vital nodes of the high-speed railway network of China is proposed,the results obtained by different parameter combinations are analyzed through simulation experiments,and determined Top20 critical nodes of the network with different time intervals,respectively.Then the evolution process of these node centrality is compared,and the reasons for the ranking fluctuation of some important nodes are analyzed.
