基于复杂网络理论的中国城市航空网络有向加权分析

为了科学优化中国航空网络资源分配、测评特殊机场的重要地位,本文运用复杂网络理论,构建中国城市航空有向加权网络,探究其网络结构特征并以度中心性、介数中心性、入强度为指标进行节点重要性排序筛选国内重要机场节点。结果表明,中国城市航空网络的节点度值和边权值分布都具有异质性,是一个无标度网络;不同方法筛选出的重要机场节点基本一致,筛选结果为网络整体管控提供有效意见;ZWWW、ZYHB机场在介数中心性相对其他指标较高,在网络中具有重要的中转作用。

Directed Weighted Analysis of Domestic Urban Aviation NetworkBased on Complex Network Theory

In order to scientifically optimize the allocation of China"s aviation network resources and evaluate the importance of special airports, this paper uses complex network theory to construct a directed weighted network of Chinese urban aviation, and explores the characteristics of its network structure. The indicators are used to rank the importance of nodes to screen the important domestic airport nodes. The results show that the distribution of node degrees and edge weights of China"s urban aviation network is heterogeneous and is a scale-free network; the important airport nodes selected by different methods are basically the same, and the screening results provide effective opinions for the overall management and control of the network; ZWWW and ZYHB airports have a higher centrality of intermediary relative to other indicators and have an important transit role in the network.
