Abstract: Shanxi water network is designed as a multi-source framework of hydraulic engineering, which overall has two longitudinal and ten horizontal trunk streams, makes the six main rivers in Shanxi inter-connected with each other and runs across almost all over the province, from east to west and south to north. For the purpose of ensuring the network to run securely and efficiently, it needs rational planning and construction as well as scientific monitoring and protection. In this paper, it extracts the topology of Shanxi water network, and then analyzes its topological properties based on complex network theory, and specifies its topo-parameters. Furthermore, the vulnerability of its network topology has been reviewed. The results show that Shanxi water network is weakly connected, the average load that the nodes and edges bear is consi-derably over-weighed, and the network transmission efficiency is not sufficient. This paper provides a decision-making strategy to select specific network nodes/edges and discusses how to supervise and guard them in management of water-network project.

摘要： 山西大水网规划为“两纵十横、六河连通，纵贯南北、横跨东西”的多源互补水网框架。考虑到水网工程的安全、高效运行，需要合理的规划建设和科学的监控防护。提取山西大水网工程的网络拓扑结构，运用复杂网络理论分析其拓扑特征，对其拓扑参数进行计算和分析，并对其拓扑脆弱性进行讨论。结果表明，山西大水网工程连通性不强，网络节点和边的平均负荷较重，网络传输效率也不高。对于选择哪些网络节点和边以及如何对这些网络节点和边进行监控和保护提供了决策参考。
