Analysis of Benefit Evaluation of Irrigation District in the Upper Jinghe River Basin Based on Fuzzy Comprehensive Evaluation Method

This paper takes the benefit of the irrigation area as the overall goal, economic benefit, social benefit and ecological benefit as the sub-objectives. Index data is set under each target, and the benefit evaluation index system of the irrigation area is established. The fuzzy comprehensive evaluation method is used as a solution to establish the benefit of the irrigation area. The mathematical model is applied to the irrigation area in the upper reaches of the Jinghe River Basin as an example to analyze and evaluate the efficiency development indicators of the irrigation area from 2012 to 2016. The benefits of the irrigation area have been improved year by year, and the evaluation results are consistent with the actual situation. The method is reliable in evaluating the benefits of the irrigation area.
