Evaluation of the coordinated development of regional water resource systems based on a dynamic coupling coordination model

Abstract

Abstract 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 model. Taking Heilongjiang, China, as an example, the results show 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.
