摘　　要：以 1个水库灌区为例 ,从节水的 3个作用分析了灌溉水资源在时间和空间上优化调度的 2个模型。优化调度不仅能减少灌区水量损失 ,提高水分生产效率 ,还能在提高灌区水分生产效率方面起明显的作用。这类节水技术对于缓解我国农业供水危机具有重要的现实意义 。With a reservoir irrigation district as example, the water saving effects of two models of optimizing irrigation water allocation are analyzed and discussed in this paper. It is thrown that water loss is reduced and water use efficiency improved with optimal irrigation water management. Optimal irrigation water allocation in irrigation areas is an effective way of alleviating agricultural water resources crisis in China.
