【目的】探究灌区节水水平评价方法，查找山东省不同灌区类型节水短板。【方法】围绕管理节水、工程节水、农业节水3个方面构建灌区节水评价指标体系，采用层次分析法和熵权法确定组合权重，基于组合权重和TOPSIS法分别对山东省14处代表灌区节水水平进行综合评价与排序。【结果】采用主、客观赋权的组合权重为管理节水0.370 1，工程节水0.489 8，农艺节水0.140 1；采用组合权重和TOPSIS法的评价排序基本一致，节水水平均表现为引黄灌区＞引河灌区＞水库灌区。【结论】灌区灌溉效益能否充分发挥是影响不同类型灌区的核心问题，其中工程节水仍是当前灌区节水水平的主要影响因素；山东省灌区在节水考核制度建设落实、执行水价合理性、灌区测墒灌溉普及率方面普遍存在节水短板；基于组合权重等比例换算为百分制应用于灌区...
