摘　　要：选取粤港澳大湾区城际高速公路路网为研究对象,采用对偶映射法建立相应的复杂网络模型,运用复杂网络特性指标节点度、度分布、平均路径长度、平均聚集系数分析其网络拓扑结构,并用随机攻击和蓄意攻击两种攻击策略,以最大连通子图相对大小、平均路径长度、网络相对效率等3个指标对该网络的鲁棒性进行评价。结果表明:网络拓扑结构上,粤港澳大湾区城际高速公路路网是小世界网络但并不是无标度网络;鲁棒性分析方面,节点度高的节点是影响路网鲁棒性的主要因素,该路网由于路网中节点度大与节点度小的节点数量相当,因此在面对随机攻击时较蓄意攻击表现得较为鲁棒。Taking the intercity expressway network of the Guangdong-Hong Kong-Macao Greater Bay Area as the research object,the corresponding complex network model is established by dual mapping method,the topology of complex network is analyzed by using the characteristics of node degree,degree distribution,average path length and average aggregation coefficient,and two attack strategies of random attack and deliberate attack are adopted,the robustness of the network is evaluated by the relative size of the maximal connected subgraph,the average path length and the relative efficiency of the network.The results show that:in terms of network topology,the intercity expressway network in the Guangdong-Hong Kong-Macao Greater Bay Area is a small-world network but not a scale-free network;in terms of robustness analysis,nodes with high node degrees are the main factors affecting the robustness of the road network.Because the number of nodes in the road network with large and small degrees is equal,the road network is more robust to random attacks than deliberate attacks.
