本文基于铁路运行网络,利用复杂网络分析方法中的中心性评价指标,对城市在铁路网络中的中心性进行了分析。我们根据列车时刻表基于L空间模型,构建了铁路运营网络,计算了铁路运营网络中节点城市的不同中心性指标,包括度中心性、邻近中心性和介中心性。这3个指标从不同角度衡量了城市在铁路运输网络中的地位和功能,我们分析了这3个中心性指标的空间分布特征及相关性,并探讨了中心性指标与城市发展之间的关系,进一步揭示铁路网络结构对城市发展的影响。
Based on the railway operation network, this paper analyzes the centrality of the city in the railway network by using the central evaluation index of the complex network analysis method. Based on the L-space model, we construct the railway operation network according to the train timetable, and calculate the different central indicators of the node cities in the railway operation network, including degree centrality, proximity centrality and centercenter. These three indicators measure the city’s position and function in the railway transportation network from different angles. We analyzed the spatial distribution characteristics and correlations of the three central indicators and discussed the relationship between central indicators and urban development , To further reveal the impact of railway network structure on urban development.
