中南半岛港口可达性结果

以中南半岛主要港口为研究对象，采用复杂网络拓扑指标中的度、平均度、平均最短路径长度、平均聚类系数、介数中心性等基础指标进行航运网络拓扑分析；并采用基于Louvian算法的Leiden社区分割算法进行网络社区划分；最后提出了基于介数中心性和连通性指数的港口出、入港可达性模型。Taking the major ports of the Indochinese Peninsula as the research subject, this study conducts topological analysis of the shipping network using basic complex network topology metrics including degree, average degree, average shortest path length, average clustering coefficient and betweenness centrality; then adopts the Leiden community partitioning algorithm based on the Louvain algorithm to carry out network community division; finally proposes a port accessibility model for inbound and outbound navigation based on betweenness centrality and connectivity index.
