摘　　要：在构建灌区灌溉用水效率评价指标体系的基础上,依据线性加权思想将基于粒子群算法的层次分析法(PSO-AHP)和粗糙集理论所得的主客观权重组合以获取组合权值并用模糊综合评价法评价灌溉用水效率。用Spearman等级相关系数检验模糊综合评价法和灌溉水有效利用系数的评价结果,其相关系数达到0.833,且各灌区灌溉用水效率的排序位次均不超过2,证明了采用PSO-AHP与粗糙集理论进行组合赋权并用模糊综合评价法评价灌溉用水效率的合理性。进一步对比两种评价结果的极值和变异系数,模糊综合评价法的1.051和0.170均远大于灌溉水有效利用系数的0.048和0.035,更有利于评价等级的划分,表明文中所采用的评价方法相对于灌溉水有效利用系数在灌溉用水效率评价领域具有明显的优越性。Through constructing the irrigation water efficiency evaluation index system in irrigation district, according to the linear weighting idea, the subjective and objective weights obtained from PSO-AHP and rough set theory are combined to obtain combination weight, the fuzzy comprehensive evaluation is adopted to evaluate irrigation water efficiency evaluation in irrigation district. The Spearman rank correlation coefficient is used to test the evaluation results of the fuzzy comprehensive evaluation method and the irrigation water effective utilization coefficient, the correlation coefficient reaches 0.833 and the ranking of irrigation water efficiency obtained by the two methods was less than 2. This proves that the rationality of adopting PSO-AHP and rough set theory to combine weighting for evaluation index, and fuzzy comprehensive evaluation to evaluate irrigation water efficiency. By comparing the extreme value and variation coefficient of the two methods, this paper finds that the 1.051 and 0.170 of the fuzzy comprehensive evaluation method are much larger than 0.048 and 0.035 of the effective utilization coefficient of irrigated water, which is more conducive to the division of rating. This shows that the evaluation method adopted in this paper has obvious superiority than irrigated water effective utilization coefficient method in the field of irrigation water efficiency evaluation.
