Abstract: The benefit evaluation of water resources is complex as it involves economic, eco-environmental and social benefits. The index system of the evaluation is a multi-level and semi-structural system including both quantitative and qualitative indexes. Based on the theory of two-level variable fuzzy decision-making model, we advance a benefit evaluation model in a irrigation area in Shanxi province. Using two-level model and improved multi-level decision-making model, the benefit of water resources in the irrigation area are evaluated in three level years of 1997,2005and 2015. The results show that the benefits are gradually increasing and the multi-level variable fuzzy decision-making model is superior to two-level model which makes the calculation results more precise. Moreover, the multi-level model can not only be used to optimize the different schemes but also to evaluate the grade of each scheme, with which to support the decision-making for the sustainable development of water resources in the irrigation area.
