摘　　要：区域农业用水量的准确估算一直是一个难题。从区域农作物种植结构分析出发,根据样点灌区单项作物灌溉定额,直接计算区域农田灌溉用水量,并进行了实例分析,结果表明该方法可得到比较合理的结果,是一种计算区域农业用水量的有效方法。Accurate estimation of regional farmland water consumption has always been a difficult problem. Analysing regional crop planting structure and making use of single crop irrigation quota in sample irrigation area, can conveniently estimate regional farmland irrigation water consumption. An actual example is given; the results show it＇s an effective method to estimate regional farmland irrigation water consumption.

关 键 词：农作物种植结构 灌溉净定额 灌溉用水量
