灌溉效益 有灌溉措施与无灌溉措施相比较，所能获得的经济效益、社会效益和环境效益的总称。由于各年可供作物生长和农田耗用的有效降雨量不同，因此灌溉供水所产生的效益也不相同，并且还与今后灌溉面积的不断扩大，管理水平的提高和农业技术发展的状况有关。 经济效益 主要有：①直接提高作物的产量和质量，增加农业收入；②间接促进农、林、牧产品加工业的发展，繁荣地区经济。一般根据试验或调查有无灌溉措施的产量资料，分析计算灌溉的增产效益。由于灌溉效益各年不同，通常用多年平均值表示。可根据灌区历年降水和灌溉效益资料，计算有代表性系列的多年平均灌溉效益；或根据有、无灌溉措施的农业产量频率曲线，用频率加权的方法计算多年平均增产效益。 社会效益 主要有：①避免农林牧各业因旱减产或失收，使供应紧张甚至发生饥荒；②由于农业增产增收，提高农民生活水平，增加城市供应，有利于各业的发展。 环境效益 主要有：①增加灌溉地区的水分，改善小气候；②改善土壤水盐运动状况，淋洗盐碱，改良土壤环境；③有利于林、草生长,增加地面植被覆盖率,保持水土，改善生态环境等。
