| Abstract: |
| 【Objective】Comprehensive evaluation of irrigation water efficiency was conducted to provide scientific basis for water-saving reconstruction and development of irrigation area.【Method】In this paper, by constructing the evalu-ation index system of irrigation water efficiency, the entropy weight TOPSIS method was used to comprehensively evaluate the irrigation water efficiency of six irrigation areas in the Second Division of Xinjiang Production and Construction Corps from 2017 to 2020.【Result】The evaluation results of entropy weight TOPSIS method are consistent with the actual situation of irrigation area. There was a strong correlation between the ranking of evalua-tion results and the ranking of effective utilization coefficient of irrigation water and the ranking of AHP-fuzzy comprehensive evaluation results ( P < 0.01 ). At the same time, the entropy weight TOPSIS method had a larger coefficient of variation than the AHP-fuzzy comprehensive evaluation results, which was more conducive to the classification of irrigation water efficiency.; According to the difference between the evaluation index grade and the comprehensive evaluation grade of irrigation water efficiency, the main control factors of irrigation water efficiency were determined.【Conclusion】Entropy weight TOPSIS method is feasible to evaluate irrigation water efficiency . In the future, with water-saving reconstruction and construction continuing, each irrigation should determine a sci-entific and reasonable irrigation system, and actively take effective measures to improve saline-alkali land, so as to improve the efficiency of irrigation water and construct modern and efficient water-saving irrigation district. |
