| 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. |
