摘　　要：为了定量化表述区域物流网络以及分析其结构特征,提出了区域物流网络表述模型。以湖南省为例,从节点度和强度分布、边的权重差异度、集聚性、节点度相关性等对区域物流网络结构进行定量分析。发现其网络为无标度网络,具有双幂律特征,边权差异度大、大节点联系紧密,拓扑结构为非同类网络等结构特征。To quantitative represent regional logistics network and study its structural features, the paper put forward a model of regional logistics network. It, to Hunan province as an example, made quantitative analysis to structural characteristics of regional logistics network from four perspectives ： node degree and strength distribution, edge weight disparity, clustering and node degree correlations, finding a few characteristics that it was scale-free network, double power-law feature, rank weighted was more differences, big nodes link closely, topology was non-similar network and so on.
