河套灌区井渠联合运用优化灌溉模型

An Optimal Irrigation model for Conjunctive Operation of Canals and Wells in Hetao irrigation District

  • 摘要: 针对河套灌区的地面水与地下水联合运用问题,提出了井渠结合优化灌溉模型,以最佳种植模式和最优工程运行策略,达到控制地下水位、防治土壤盐碱化、获得农作物稳产高产的目的.模型有调蓄地面水源、土壤贮水层、地下含水层的能力.优化计算成果与266.7hm2试验示范区的实际运行结果相吻合,节水、节能、增产及控制地下水位、改良盐碱地等效果十分显著,这对发展节水型灌溉农业具有重要的现实意义.

     

    Abstract: An optimal irrigation model of combining wells and canals is presented in Hetao irrigation district for conjunetive operation of surface water and groundwater. In the model the optimal planting plan and the operation policy are used in order to control the groundwater level and soil salinization and get steady and high harvest. The model is able to adjust the surface water, the water in the soil moisture belt and the aquifer cooperatively. The results are in agreement with that of the experiment area of 266.7hm2. Its effect is obvious in water-saving, harvest-increasing,groundwater levelcontrolling and soil-ameliorating. It has important significance for developing watersaving irrigation agriculture.
