灌区多种作物间灌溉水量的最优分配

Optimal Allocation of Irrigating Water for Manifold Crops in an Irrigated Area

本文针对灌区内的多种作物并存,不同种类作物有其不同的需水规律的情况,探讨并建立了在非充分灌溉条件下,灌溉季节内多种作物间水量优化分配的双层 DP 模型,该模型两个层次分别以水量优化分配和灌溉区经济效益为决策目标,可有效地实现节水灌溉高产稳产的优化策略.通过在景泰川灌区的实例应用,论证了该方法的有效性.

In an irrigated area,there are always diversified crops each of which has adifferent but regular demand for water.A dynamic pvoqramming model of optimal allo-cation of irrigating water for different types of crops is put forward here.In order toacliece the goal og high yield and economical irrigation,the model has taken optimalwater allocation and maximum economic bendfits as its tarqet.The method has been putinto practice in the Jintai Irrigated Area,and its effectivenese has been ascertained.
