摘　　要：基于复杂网络理论,系统分析了中国沿海港口网络的度分布、网络集聚系数、平均路径长度、可达性及其相互关联性。结果表明中国沿海港口网络空间结构特征差异明显,表现出较强的集聚性,其度累计概率分布表现为具有置信度较高的指数分布,且具有较小的路径长度和较大的集聚系数,整体结构呈现"小世界网络"特点。并结合实际的自然,社会因素对其进行分析,为今后港口建设规划和航线分布提供有力的理论支持。China＇s coastal port network＇s degree distribution,the clustering coefficient,the average path length,accessibility and their relationship are analyzed based on the complex network theory.The results indicated that the spatial structure feature differences of China＇s coastal port network are significant and have a strong concentration.The cumulative probability distribution of degree has exponential expression of high confidence and China＇s coastal port network has a relatively small average path length and a relatively large cluster coefficient.Combined with the nature and social factors,the research could provide powerful tools supporting for the management of the ports and the distribution of the sea routes.
