Abstract:: An improved TOPSIS evaluation method, which aimed at comprehensive evaluation of the operation condition of irrigation areas and water-saving reconstruction benefit in recent years, was proposed in this paper. Some characteristic indexes affecting the operattion condition of irrigation areas were selected as evaluation indexes, information entropy was introduced to calculate the weight coefficient of each index and to comprehensively evaluate the operation condition benefit by using the close degree in irrigation area. The analysis result shows that the relative closeness evaluation of the optimal solution sample in 2006 was the largest and the operation conditions of the irrigation area were optimal in 10 years in the water-saving reconstruction of irrigation. It overcomed the impact of expert appraise and the materials of sample. The results indicated that the calculation principle of this model was scientific and simple，and its result of calculation process was reasonable. It can offer scientific basis and good reference for comprehensive evaluation of the operation condition benefit in irrigation areas.
