Comprehensive evaluation of water resources system stress in Shanxi province
摘要
Abstract
In view of extreme drought condition,coal exploitation and watering safety,an evaluation index system for the water resources system has been established to consider the stresses of water resources,water environment,water safety and water environments in Shanxi province.Evaluation criterions for stresses of low-degree,medium-degree and high-degree were developed with reference to the existing criterions of China and overseas.The indexes were standardized with an analysis on the effect of index variation on system stress by principle of diminishing marginal utility.A method of fuzzy matter element combined with Euclid approach degree was applied to the calculation of these stresses.The results indicate that the stress of Shanxi falls in the medium-degree,and the cities of Yangquan,Shuozhou,Lvliang,Jinzhong and Linfen also in this range,while Taiyuan,Datong and Yuncheng fall in the high-degree,and Changzhi,Jincheng and Xinzhou in the low-degree.The index system and the method provide a device of accurate evaluation on the actual status of water resource stress,and they are verified effective,universal,simple and practical.关键词
