便捷稳定的高速铁路运输网络是铁路客货运高效运输的保证,以复杂网络理论为基础,从铁路实际基础设施角度构建高速铁路网络,从网络拓扑性质方面分析高速铁路网络特性,了解高速铁路网现状.运用LSpace方法构建高速铁路网络模型,从度与度的分布、平均路径长度、聚集系数等复杂网络指标分析拓扑网络结构特征.研究得出,我国高速铁路网络整体上具有无标度网络特征,中东部和沿海沿江地区车站数量较多,聚集性较高;局部枢纽地区的节点连接聚集,具有小世界网络特征,主要集中在杭州南、南京南、郑州东等大型车站.此外,通过对比分析2023年高速铁路网络特性的变化情况,可以看出路网车站具有连通性不断增强、路网区域布局均衡化发展的特征.
Analysis on Structural Characteristics of High Speed Railway Network Based on Complex Network
A convenient and stable high speed railway transportation network is the guarantee for efficient railway passenger and freight transport.Based on complex network theory,this paper constructs a high speed railway network from the perspective of actual railway infrastructure,analyzes its characteristics from the aspect of network topological properties,and understands its current situation.This paper constructs a high speed railway network model by L Space method,and analyzes the structural characteristics of the topological network from complex network indicators such as degree distribution,average path length and clustering coefficient.The study shows that China's high speed railway network has the characteristics of scale-free network as a whole,with a large number of stations in the central and eastern regions and coastal and riverside areas and high aggregation.Nodes in local hub areas are connected and aggregated,showing the characteristics of small-world network,mainly concentrated at large stations such as Hangzhou South,Nanjing South and Zhengzhou East.In addition,by comparing and analyzing the changes in the characteristics of the high speed railway network in 2023,it can be seen that the stations in the railway network have the characteristics of increasingly enhanced connectivity and balanced development of the regional layout of the railway network.
