Evaluation of Water Resources Sustainable Utilization in Wuhan Based on the Model of SUDE

Abstract

SUDE model is a systematic sustainable use model based on the view of the whole life cycle of water resources. The analysis of the model water resources has been divided into four stages according to the state of motion water resourcesat different times in its life cycle, namely the water supply stage (“S”),water use phase (“U”),water collection,treatment anddrainage stage (“D”) and water return to natural ecological (ecology) environment for dilution, degradation stage (“E”).on the analysis above,SUDE theoretical model of water system has been built and corresponding evaluation index systemhas therefore been established. Then, we use entropy weight TOPSIS method to evaluate thesustainability of water resource during 2013∼2017 yearsin Wuhan, and finally the corresponding conclusions and suggestion have been drawn according to the result of evaluation in the paper.
