摘要:
以我国主要代表性城市为研究对象, 分析高速铁路网络特性与拓扑特征, 识别高铁网络中的节点城市及其功能作用。运用Space-P方法构建高铁网络模型, 利用复杂网络理论及Pajek分析软件, 从度值、平均路径长度、聚集系数及节点城市中心性等方面研究我国高铁网络的拓扑结构及节点中心性, 结果表明: 我国高铁网络整体聚集性较高、连通性较强, 东中部及沿海城市表现出高聚集性, 西部城市高铁网络连通性低, 聚集性较弱; 高铁网络具有小世界特征, 任意两节点之间通过较少的中转次数即可连通, 少数城市间需中转三次才能连通; 在高铁网络中, 度值较大的城市主要集中在我国东中部及沿海地区, 西部及东北地区城市度值较小且度中心性较大, 其接近中心性也较大; 而度值较小且介数中心性较大的城市具有较强的中转能力。
