Research on the Countermeasures of the Reduction in Water Transfer from the Yellow River in Yinchuan Plain, China.

Abstract: Aimed at the problem of water shortage for irrigation while reducing the water transfer from the Yellow River in Yinchuan plain, by using hydrogeological numerical model, this paper proposed a set of solutions of combining well irrigation and channel irrigation to satisfy the water demand of agriculture. The result shows that, when the reduction is less than 400 million m³/a, increasing well irrigation can meet the demand of agriculture, while the reduction is between 400 and 930 million m³/a, increasing well irrigation as well as decreasing the field irritation quota can also work. But as for the reduction is greater than 1 billion m³/a, we cannot meet the demand of agricultural irrigation, and this will have great effect on the social economy and ecological environment.
