摘　　要：从社会学的角度,以珠江流域广东、广西21个港口城市组成物流引力网络,用社会网络分析方法对该流域物流网络的基本网络特征进行研究,探讨了流域物流节点城市的空间层次结构。采用物理学万有引力公式与珠江流域沿线21个港口城市货运量相结合,建立了货运量万有引力模型,计算得出珠江流域内城市之间的物流引力矩阵,然后应用社会网络分析方法及其工具软件Ucinet分析了珠江流域物流网络结构性问题。In this paper, with the logistics gravity network composed of twenty-one port cities in Guangdong and Guangxi along the Zhujiang River Watershed as the object, we used the method of social network analysis to study the basic characteristics of the logistics network of the belt and discussed the spatial hierarchical structure of the nodal cities. Then we used the physical formula concerning gravity to analyze the freight volume of the twenty-one cities and established the freight volume gravity model. Through calculation, we obtained the flow gravity matrix among the cities and then applied social network analysis and its software Ucinet to the structure of the logistics network of the Zhujiang watershed.
