摘　　要：针对高速铁路网络性能评估问题,目前研究中存在多种维度和特征的评估指标,缺乏不同指标间的比较分析。选择站点拓扑维度指标(度中心性DC、接近中心性CC、介数B),站点功能维度指标(关键性SI、重要性SC、强度SS),以及网络整体维度指标(集聚系数、网络密度、平均路径长度),应用于京津冀、东北、西南3个区域的高速铁路网络性能评估,比较并分析了不同维度指标的特征、相关性和适用性。结果表明:SC指标可以量化不同区域高速铁路网络的差异,B指标对于拓扑简单的网络适用性差;DC,SI,SC,B 4个指标之间的相关性较强,而CC,SS2个指标与其他指标相关性较弱;京津冀地区高速铁路网络的连通性、密集程度均大于其他两地区,网络聚集系数评估区域高速铁路网络性能时会导致不合理的结果。In terms of network performance assessment of high speed railway networks,the current research uses indicators of different dimensions and characteristics,where the comparative analysis among different indicators is insufficient.This paper selected six station-level indicators of topology dimension and functionality dimension,and the indicators of the whole network level for indicator comparison.The station-level topology indicators include degree centrality(DC),closeness centrality(CC),and betweenness(B).The station-level functionality indicators include station criticality(SC),station importance(SI),and station strength(SS).The network-level indicators include agglomeration coefficient,network density,and average path length.These indicators were implemented in the performance assessment of the high speed railroad networks in the Beijing-Tianjin-Hebei region,northeast China region,and southwest China region,and the characteristics,correlations,and applicability of the indicators were compared and investigated.The results show that the SC indicator can appropriately quantify the variety in different regional networks,while the B indicator is not capable of distinguishing the variety of stations in the networks with simple topology.The correlations among the four indicators DC,SI,SC,and B are strong,while the CC and SS indicators are weakly correlated to the other indicators.Moreover,the connectivity and density of the high speed railway network in Beijing-Tianjin-Hebei region are greater than those of the other two regions,while the aggregation coefficient indicator is not suitable for the performance evaluation of the regional high speed railway network.
