作物缺水条件下灌溉供水量最优分配

The optimal allocation of irrigation water with diversified crops under limited water supply

针对灌区水源短缺情况，建立了一种对有限水量在多种作物之间进行最优分配的两层分解协调模型：第一层为基于作物水分生产函数，求解单作物非充分灌溉条件下最优灌溉制度的动态规划模型；第二层为将有限水量在多种作物之间进行最优分配的动态规划模型实例计算表明。

This paper presents a 2 level decomposition coordination model for the optimal allocation of irrigation water with diversified crops in case of limited water supply.The first level of the model is designed to produce the optimal irrigation schedule of a single crop by using dynamic programming.The second level is used to solve the optimal allocation of irrigation water among crops.A case study shows that the model is reasonable and feasible.
