| 摘 要： | 为了评价灌区节水改造后的运行状况和分析近年来节水改造的综合效益，提出了一种灌区运行状况评价的改进TOPSIS模型评价方法，选择影响灌区运行状况的主要因素作为评价分析的特征指标，引入信息熵来计算各评价指标的权重，利用求得的贴近度综合评价灌区的运行状况。通过某灌区实例分析可知该灌区在10 a里的节水改造中，2006年的评价样本最优解的相对贴近度最大，灌区运行状况最优。该方法克服传统的TOPSIS法在确定评价指标的权重因子时采用专家意见打分或单一样本材料造成主观因素的影响，计算过程简单科学，结果合理，可为灌区节水改造后的运行评价提供科学依据和良好思路。

| 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. |
