摘要

在灌区节水改造项目综合后评估中，指标权重的确定对于评价结果的客观合理性起着至关重要的作用。为了科学合理地确定指标权重，选用两种不同原理的综合赋权法对灌区节水改造资源性效益评价指标权重进行了确定，并分别应用得出的权重值计算了灌区节水改造资源性效益综合评价值。结果表明，两种综合赋权方法得出的指标权重向量大小排序结果一致，应用于灌区评价时所得4个灌区节水改造资源性效益两种综合评价值大小不一样，但排序结果一致。最后，对该结果出现的原因及两种综合赋权法的适用条件进行了分析。

Abstract

Reasonable determination of index weight is of great importance to get an objective and reasonable evaluation result of water saving and improvement evaluation in irrigation district.In order to obtain the objective and reasonable index weight

two kinds of combination weighting method with different principles are applied to index weight calculation and the calculated result are applied to benefit evaluation of water saving and improvement in irrigation district.It is found that the two kinds of index weight vector sequences are the same. The sequences of the two kinds of evaluation result for four irrigation districts based on the two kinds of weight are the same though the evaluation values are different.Finally

the causes of the result and the application condition of the two kinds of combination weighting method are analyzed.
