区域水资源系统耦合协调分析对促进区域水资源系统的可持续协调发展具有重要作用。本文引入动态耦合协调模型研究水利枢纽的协调发展问题。采用改进的熵权法确定各指标的权重。利用该模型可以得到水资源子系统与其它子系统以及整个水资源系统之间的耦合度和协调度。结果表明，2005-2014年黑龙江省水资源系统呈现出低耦合、低协调的特征，资源子系统与社会经济、生态子系统之间存在实质性矛盾。因此，加强水资源与社会、经济、生态的统筹发展，提高资源子系统与各子系统的耦合能力，是促进水资源系统协调发展的有效策略。
Coupling and coordination analyses of regional water resource systems (WRS) play an important role in promoting the sustainable and coordinated development of those systems. In this paper, a dynamic coupling coordination model is introduced to study the coordinated development of WRS. The weight of each index is obtained using an improved entropy weight method. The coupling and coordination degrees between resource subsystems and other subsystems and an entire system of water resources can be obtained using this mentioned model. Taking Heilongjiang, China, as an example, the results showed that in 2005–2014, the WRS exhibited low coupling and low coordination characteristics due to a substantial contradiction between the resource subsystem and the social and economic and ecological subsystems. Therefore, strengthening the overall development of water resources, society, economy and ecology and improving the coupling abilities between resource subsystems and each of the other subsystems are effective strategies for promoting the coordinated development of WRS.
