At last, A drought index model was developed by considering the water requirement of winter wheat and the available soil water content.
最后，根据冬小麦的需水规律和土壤有效水含量构造干旱指数模型。
In the arid and semiarid region, plant decreases the depth of rainfall-moistened layer in soil. The available soil water distributes to shallow layer.
在干旱半干旱地区，植被影响着降水在土层中的分布及地表的蒸散条件，使土壤有效水向浅层分配。
