Abstract: In order to research properties of traffic network of urban agglomerations, it designs the model of urban agglomeration by dual approach, and calculates the effective size, efficiency, constraint, hierarchy of the structural holes theory by VC ++6.0 and Matlab7.0. It calculates 1-cliques of the traffic networks of urban agglomeration of Chang-Zhu-Tan by using n-cliques algorithm. The conclusion is that the five roads are rare, accounting for 0. 24%, and more than five roads do not exist in 1-cliques of the cities networks of urban agglomeration of Chang-Zhu-Tan. The conclusion demonstrates that according to hierarchy, the traffic networks of urban agglomeration of Chang-Zhu-Tan can be divided into core road, intermediate road, and marginal road; the structural autonomy and invalid roads do not exist in the cities networks of urban agglomeration of Chang-Zhu-Tan.

Key words: complex networks, urban agglomeration, structural hole, n-cliques, structural autonomy

摘要： 为了深入研究城市群交通网络结构特性，根据长株潭城市群交通网络构建其道路对偶网络，建立网络结构洞算法，运用VC++6.0连接Matlab7.0计算长株潭城市群交通网络的有效规模、效率、约束度、等级度等结构洞理论指标值，对网络使用n-派系算法计算长株潭城市群交通网1派系结构分布，长株潭城市群交通网络1-派系中包括五条道路以上的不存在，包括五条道路极少，占0.24%，包括四条道路较少，占13%。可以得出以下结论：按照等级度指标可将长株潭城市群交通网道路划分为核心、中间、边缘三类；长株潭城市群交通网络不存在着结构自治，在结构上不存在无效道路。
