海上丝绸之路航线网络的连通性建模与仿真研究

为推进海上丝绸之路航线网络的建设与完善，基于复杂网络的相关理论，从局部和全局两个角度对不同攻击模式和应对策略下网络的连通性进行了研究.结果表明，海上丝绸之路航线网络在节点随机攻击下的抗毁性较强，而在选择攻击下，网络的连通性较差；对于提高航线网络连通性，甩港策略的效果要更优于重要港口保护策略.同时，不同测度下，对网络连通性影响较大的港口多为东亚和东南亚地区介数较高的港口，在对网络进行连通性优化时，可根据介数确定各个港口在网络中的重要性.

Research on connectivity modeling and simulation for route network of Maritime Silk Road

To promote the construction and optimization of Maritime Silk Road route network， the network connectivity is studied under different attack strategies and countermeasures from two views of local and global， which based on the related theory of complex network. The results show that the route network of Maritime Silk Road is robust under random attack and the connectivity is poor under selective attack. The countermeasures of skipping ports and protecting important ports is able to improve the network connectivity， and the effect under skipping measure is better than that under protecting measure. At the same time， the ports that have larger impact on network connectivity always be the ports with higher betweenness which located in East Asia and Southeast Asia， so betweenness can be used to determine the importance of ports when optimizing the network connectivity.
