摘要
通过确定干旱指标，计算干旱指数，将干旱指数分几个等级，表征干旱程度，再将这些特征值直接运用到人工增雨作业中，取得了明显的效果。
n order to combat drought and get bumper harvest,it is an important measure to carry out artificial precipitation enhancement in time based on the drought situation. Agricultural drought has relations not only to rainfall but also to spatial and temporal distribution of precipitationBased on drought criterion,drought index is calculated and is divided into sevenal degrees to show the extent of drought. These characteristic values are then used directly in the operation of artificial precipitation stimulation and obvious effect is obtained
