两层结构模型在局部区域水资源优化配置中的应用

Application of Double-layer Construction Model in Optimum Water Distribution of Some Areas

基于以非充分灌溉理论,建立了灌区作物优化配水的两层结构模型,第一层为单一作物的优化配水模型,第二层为灌区各作物间优化配水模型,引用地表水作为一个来水过程,从而使模型更加符合实际情况.该模型用于河南省原阳县堤南灌区水资源优化调度研究,结果表明模型合理实用,为该灌区提高用水效率、节约用水提供了科学依据.

Based on the theory of insufficient irrigation, two construction models with the method of mathematic programming are set up and optimum water distribution to the crop of the irrigating areas with double_layer construction models of water distribution is established. The first layer is optimum distribution to a single crop; the second layer is the optimum water distribution model among all kinds of crops. The adducted earth's surface water is used as a water source for the process of irrigating, making the model more matched the actual circumstance. This model is used in the research of optimum water distribution at dike south irrigating area of Yuanyang county of Henan province. The result has indicated that the model is reasonable and practical, providing a scientific gist to conduct effective irrigation and water conservancy of the area.
