摘　　要：以唐山市公交系统为研究对象,构建网络模型。在L空间和P空间分别研究唐山市公交系统静态网络性质,包括网络的聚类系数、平均路径长度和度分布。结果表明,唐山市的公交网络具有较大的聚类系数、较小的平均路径长度和指数形式的度分布,具有典型的小世界网络的特征。In this paper, we studied a network model based on the Tangshan urban bus system. Several static statistical properties of the network in space L and space P have been investigated respectively, including the clustering coefficient, the average path length and the degree distribution of nodes. The analysis on the data indicates that the urban bus network of Tangshan has a large clustering coefficient, a small average path length and the exponential degree distribution of nodes. The Tangshan urban bus system belongs to a small-world network.
