Abstract
The drought is another main hazard restraining agricultural production in the lowland area, which is composed mainly of lessive clay soil. And it often occurs during the end of Spring and the begining of Summer while the wheat is in the ear, the soy bean bears pods and corn is in the heading period. All of them are in key growing season. This paper took Qi Hulin basin as an example, using water resources model FLOWAT, to numerically analyse water distribution and soil water variation. The results show that the drought seriously lowers the crop production. In order to keep up high and steady crop production, some drought relief measures and irrigation methods are presented.
