Evaluating Index System and Methods of Regional Water Resources Sustainable Utilization

Water is the source of life and on which human being exists and social economy develops sustainable. There still remain many problems challenging the sustainable water resource utilization, such as imbalance between the demand and the supply, the low efficiency utilization and the worsening water environment. So the studying of evaluating index system and methods of regional water resource sustainable utilization becomes the prior problem to solve. On the base of realizing the current situation and developing tendency, the accurate evaluation of the sustainability of water resources is attached more and more important. By leaning the summary of lots of systems in evaluating the sustainability of domestic and foreign, the problems of methods and index system are summarized. It is pointed out that there remain problems that it’s still something wrong with the method to build the index system and that there’s limitation in characteristic index. Simultaneously, by analyzing the present evaluation method, it is admitted that subjective weighting is easy to realize but with a comparatively worse accuracy, while objective weighting can utilize the data completely but is too fussy to operate it. No-weighting method like ANN is easy to operate, but it mostly depends on the fake data. At last, the problem and development tendency are summarized to attract some new opinions of studying the sustainable regional water resources utilization and push the improvement of the evaluation system of sustainable water resources utilization.
