摘要：
From the dependence of winter wheat on water for growth a study is conducted of drought intensity and probability as well as their impacts upon the yield, whereupon are developed models for venture evaluation of drought damage to the crop grown in Henan province, with which to make the venture evaluation and regionalization of drought effects to provide scientific basis for modifying crop structure and preparing countermeasures for preventing and alleviating drought loss.
