采用人工模拟降雨方法，以谷子为对象，在3°～15°的坡地小区上分析研究了谷子坡地的入渗特征。结果表明：在实验条件下，入渗率随时间延长虽有小的波动，但总体呈下降趋势，符合幂函数规律，且与对照相比，能提高土壤入渗量；从拔节初期到灌浆初期，谷子坡地的入渗能力逐渐增加；Kostiakov、Horton、Philip和蒋定生入渗模型拟合证实，Kostiakov模型适合谷子全生育期水分入渗模拟，但估算量平均偏低10％。

By taking Millet as the research object ,the characteristics of soil water infiltration are studied in the runoff plots (3°、5°、10°、15°) by adopting the method of artificial simulation rain‐fall .T he results show that the infiltration rate in millet slope farmland generally presented a de‐creasing tendency and fitted with the power function laws with a small fluctuation of time prolong in infiltration rate under the experiment conditions .Compared with the control group ,the accu‐mulated infiltration amount in soil can be increased .Infiltration rate in Millet slope land can grad‐ually increase from early jointing to milk‐filling stages .It has been proved through the infiltration model fitting of Kostiakov ,Horton ,Philip and Jiang Dingsheng that Kostiakov model can adapt to the moisture infiltration simulation during the w hole stage of millet grow th and development , but the estimated amount is 10% lower than the average values .
