Abstract:

With continuing population growth and rapid economic development,coupled with increasingly serious water pollution,growing shortage of available water resources,water crisis shows up in many regions.Evaluation of the regional water shortage is the basis for the study of water resources risk. Previous studies, with the use of a single evaluation method, resulting in differences in evaluation results. In this paper, the circulating correction model derived from a single evaluation method generated a combination correction of the evaluation results. Comprehensive evaluation index system constructed indicates water shortage in Yunnan Province as well as aspects of water economics,construction control,water supply,water usage and water environment. The use of fuzzy matter-element, fuzzy pattern recognition, and other single evaluation method, finally, gains a combination of three evaluation methods, namely, average method, Boarda method and Compeland method for the different evaluation results.The Kendall test and Spearman test methods were carried out for pre-and post-conformance tests to ensure reliability of the model cycle correction in this paper. The establishment of the degree of shortage of water resources evaluation model based on the circulating correction mode and application, gives the present status of Yunnan Province including 16 cities in terms of degree of water shortage as well as the lack of water type in 2010, and corresponding countermeasures are put forward.

Key words: water shortages, evaluation of the extent of the shortage, circulating correction mode, combination evaluation, Yunnan Province
