熵权模糊物元模型在节水灌溉综合效益评价的应用
Application of entropy weight fuzzy matter element model in comprehensive benefit evaluation of water saving irrigation
摘要
Abstract
In view of shortcomings in multiple simple index comprehensive evaluation methods in com-prehensive benefit evaluation of water saving irrigation in the past,an entropy weight method is used to determine the weight of each evaluation index,and a matter element extension model based on the en-tropy weights is established to evaluate the comprehensive benefits of water saving irrigation in irrigation districts.An evaluation index system is developed by taking three aspects such as social,economic and ecological benefits into consideration.Four irrigation districts in Ji′an City are evaluated with the me-thods and models.The results show that the comprehensive benefit level is fair in the Yinwan Bridge irrigation district,but the benefit levels are becoming fair,good and fine in the Tiannan,Guko and Nanche irrigation district,respectively.The stability of the results are verified by sensitivity analysis method.The study shows that the entropy weight analysis method has a certain application significance in the comprehensive benefit evaluation of water saving irrigation.关键词
