Water resources evolution direction distinguishing model based on dissipative structure theory and gray relational entropy

Based on the assumption of water resources system is a dissipative structure,the water is regarded as a sequential parameter to describe the sequence and evolution direction of system.According to the synergetics theory economy,social and ecological subsystem should coordinate with each another,in order to maintain the water resources system as an sequential system.The dissipative structure theory and gray system theory are applied to establish the distinguishing model.The model is applied to evaluation of the water resources evolution in Yellow River basin.
