灌溉水资源最优分配的DP-DP法

Two Level DP-DP Model for Optimizing Multicrop Allocation of Irrigation Water

  • 摘要: 在缺水地区,为了增加农作物产量,实行节水灌溉和对有限的灌溉水资源进行最优分配至关重要。因此,提出了一种对有限灌溉水量在多种作物之间进行最优分配的两层动态规划的迭代方法(DP-DP法):第一层求单作物最优灌溉制度;第二层对有限灌溉水量在多种作物之间进行最优分配,总目标是使灌区的总效益最大。算例验证表明,模型合理,方法切实可行。还设计了通用高效的FORTRAN语言程序包,有利于方法的推广应用。

     

    Abstract: Scheduling and determining of irrigation water applications are importart considerations to increase coneern about agriculture productivity in a region of water shortage. In this paper, a two level DP-DP model has been constructed to optimize multicrop allocation of irrigation water in order to increase the benefit of whole region: The first level is to design the optimal irrigation schedule of a single crop;The second is to determine the optimal allocation of irrigation water among crops given limited water resources. A case study example indicates that the model is reasonable and the procedure is feasible. Computer programs utilized in this paper are available from the author.
