摘　　要：针对多水源多作物灌区,研究有限供水条件下灌区优化配水问题。模型中既考虑水库优化调度,又考虑田间优化配水。模型思路:根据灌区水土资源分布状况,将全灌区划分为多个子区,每个子区种植有若干种作物。如果把每个子区每种作物所在的田块看作一个土壤水库,则可采用水库群调度的方法研究这类灌区优化配水问题,文中采用的是优化控制方法。为了证明模型的正确性,同时建立了3个模型。模型1:既不考虑水库优化调度又不考虑田间优化配水;模型2:只考虑水库优化调度;模型3:只考虑田间优化配水。实例计算表明,整合调度模型能产生较多的效益(特别在干旱年份),优化控制方法计算性能良好。The optimal water allocation under limited water supply is studied with a multisource and multicrop irrigation area as a background Both optimal reservoir operation and optimal allocation of water to lands are considered in this paper.The whole irrigation area is divided into units according to the distribution status of water resources and land resources.On every unit is planted several crops.If the field where each crop in each unit is planted is looked upon as a soil reservoir, the optimization methods employed in the operation of multireservoir system can be used to study the optimal water allocation in irrigation area.The optimal control algorithm is employed in this paper.To show the validity of the integrated model, the three different models are simulated in this paper.In model I, neither reservoir nor canal irrigation systems is operated optimally.In model Ⅱ, only optimal operation of reservir is considered.In model Ⅲ, only optimal operation of canal irrigation systems is considered.The case study shows that the integrated model can generate more benefit than the other three models, especially in drought years, and the optimal control algorithm performs well.
