灌溉用水量灌溉用水量amount of irrigation waterguan’gai yongshuiliang灌溉用水量(amount of irrigationwater)灌溉土地需从水源取用的水量，通常以立方米计。它是灌区规划设计和管理运用的重要数据。灌溉用水量包括作物正常生长所需灌溉水量与渠系输水、田间灌水所损失的水量之和。作物正常生长所需灌溉水量称净灌溉用水量，也叫有效灌溉水量，特殊条件下还包括为改善作物生态环境如防霜冻、风蚀、大气千旱、洗盐、调节土温，喷洒农药等需用的水量。加上从水源到田间的损失水量后叫毛灌溉用水量。一种作物某次灌水的净灌溉用水量用下式求得: M刀二m‘创式中M刀为作物某次净灌溉用水量(立方米);脚为作物某次灌水定额(米“/亩);田为作物的灌水面积(亩)。一种作物某次灌水的毛灌溉用水量为:rr一功矛V︸一刃 一一峋式中Mg为作物某次毛灌溉用水量(立方米);刀w与灌溉水利用系数。全灌区(或种植区)一个时段净灌溉用水量M，、可由同期灌水的各种作物的M，叠加得出，也可用此时段的综合净灌水定额卿。。与各种作物总的灌水面积之积算出。全灌区(或种植区)一个时段毛灌溉用水量M‘g可用下式计算:M烤=一种作物全生长期的灌溉用水量(包括播前水)称为该种作物的灌溉用水量。全灌区各种作物在一年内的灌溉用水量称为灌区的灌溉用水量。不同年份(如干旱年、中等年、湿润年)的灌溉用水量不同，因此，多采用多年平均值为指标。灌溉用水量的大小及其在多年和年内的变化情况，与有效降水，各种作物的灌溉制度，灌溉面积以及渠系输水和田间灌水的损失等因素有关。 (朱光大)
