Research on the countermeasures of the reduction in water transfer from the Yellow River in Yinchuan Plain, China

摘要

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 m~3/a, increasing well irrigation can meet the demand of agriculture, while the reduction is between 400 and 930 million m~3/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.
