摘　　要：基于复杂网络理论建立高速公路网络演化模型,并对该模型的度和度分布关系进行分析。分析结果表明,该类型网络最终会演化成无标度网络,具有小世界性特征。为了研究该网络在遭受不同性质攻击时网络具有的连通效能性,对江西省高速公路网络分别进行随机性和选择性攻击,结果表明,网络的连通效能性与移除节点的数量有很大的关系,在遭受不同性质攻击时均具有一定的连通效能性,但在遭受选择性攻击时,网络迅速分裂成众多子网络,连通效能性急剧下降为0,网络在短时间内就处于崩溃状态,为高速公路的规划、建设提供依据。The relationship between degree and degree distribution through the establishment of the network model of the expressway network was analyzed based on the complex networks theory,which showed that this type of network would eventually evolve into a scale-free network with a character of small world. In order to study the connected efficiency of the networks when subjected to different attacks,the highway network of Jiangxi province was attacked randomly and selectively and the result showed that the connected efficiency of the network had a great deal to do with the amount of the removed nodes,the network had a certain connected efficiency in different kinds of attacks,however,it quickly split into many subnetworks in a selective attack,its connected efficiency dropped sharply to 0 and the network was in a state of collapse in a short time,which could provide scientific basis for the planning and construction of the highway.
