为掌握长三角地区高等级航道网络特性，加强航道的维护和对事故的应急处理能力，基于复杂网络理论对长三角高等级航道网络特性和鲁棒性进行分析.建立考虑航道通航等级的长三角地区高等级航道加权网络拓扑模型，分析网络统计特性，识别航道网络关键节点和航段.对航道网络的边（航段）受到随机攻击、基于边强度的蓄意攻击（蓄意攻击Ⅰ）和基于实际网络的边介数中心度的蓄意攻击（蓄意攻击II）等三种攻击模式下的变化规律进行仿真.结果表明，长三角高等级航道网络具有无标度网络的特点；航道网络中存在网络关键节点和航段, 需要加强管理和维护；在随机攻击下, 航道网络具有较强的鲁棒性；网络效率下降到50%情况下，网络可承受蓄意攻击Ⅱ的次数约为蓄意攻击Ⅰ下的30%，约为随机攻击下的25%；在蓄意攻击II下，网络鲁棒性较差，蓄意攻击I下的鲁棒性优于蓄意攻击II，其鲁棒性更偏向随机攻击下的表现.分析结果对长三角地区高等级航道网络的规划和管理，保障航道网络畅通和水上交通安全，促进水路运输发展具有参考意义.

In order to understand the characteristics of the Yangtze River Delta high-level waterway network, and facilitate the maintenance of the waterway and the emergency response capability of the accidents, the characteristics of the Yangtze River Delta high-level waterway network and robustness were analyzed based on the complex network theory. A weighted network topology model of Yangtze River Delta high-level waterway network considering the navigation grade was established to analyze the statistical characteristics of the network and identify the key nodes and waters segment of waterway network. The variation law of the waterway network under three attack modes, including random attacks, attacks based on edge strength, and intentional attacks based on the edges betweenness centrality of the waterway network was simulated. The results show that the Yangtze River Delta high-level waterway network has the characteristics of a scale-free network; there are key nodes and waterway segments in the waterway network, that need to strengthen management and maintenance; the waterway network has strong robustness under random attacks; when the network efficiency drops to 50%, the number of the network can withstand intentional attacks II that the network can bear is about 30% of that under intentional attacks I, and about 25% of that under random attacks; under intentional attack II, the network robustness is poor, and the robustness under intentional attack I is better than intentional attack II, and its robustness is more biased towards random attacks. The analysis results provide reference significance for the planning and management of the Yangtze River Delta high-level waterway network, ensuring the smoothness of the waterway network and the safety of maritime transportation, and promoting the development of maritime transportation.
