蜻蛉河大型灌区水资源优化配置模型

 根据非充分灌溉理论，按大系统分解协调原理，建立了以总效益最大为目标的灌区灌溉水资源递阶控制优化模型，对灌区多水源进行优化配水研究。应用上述数学模型，对蜻蛉河大型灌区进行水资源优化配置研究。对于每个层次子系统，采用适宜于解决多阶段过程或能转化成多阶段决策过程的动态规划方法来求其最优解。计算结果表明：本文引用和提出的理论与方法是正确的。同时也使我们看到，经过水资源的合理优化分配，采用非充分灌溉方法将具有较大的节水潜力，此研究成果为灌区水资源合理利用提供了一种新途径。

The Water Resources Optimal Allocation in Qingling River Irrigated Area Based on Deficit Irrigation

In according to the decomposition coordination principle of large scale system, the optimal allocation model of water resources in regions is established on the theory of deficit irrigation. Based on this theory, the model was used to study the water resources optimal allocation in Qingling river big irrigation area. For every layer subsystem, in order to optimize the calculated result，the suitable solving multi-phases process methed or multi phases decision making process dynamic plan method could be adopted. The case showed that the theory and method this dissertation adopted were right. At the same time, utilization of the water resources optimal allocation and deficit irrigation method provide a new way to rational use water resources with large potential of water saving.
