| 摘 要： | 在黄土高原南部地区 ,通过人工模拟降雨试验 ,探讨了各因子对水土流失特征值的作用效应。结果表明 ,起流历时、径流模数主要受雨强和耕作措施影响 ;产沙模数主要受雨强和坡度影响。同时 ,建立了水土流失预报模型 ,在给定定义域的前提下 ,提高了方程的精度 ,并且为该模型在以后的应用增加了适用范围

| Abstract: | This paper discussed the effect of some factors on characteristic value of soil and water loss,which has been completed by simulating rainfall experiment in the south region of the Loess Plateau.Runoff starting time and runoff modulus,were mainly affected by rain intensity and farming measure,while rain intensity and slope are major factors to sediment modulus.At the same time,soil and water loss prediction models were established with given definition scope,which improved the model's precision with better application potential. |

| Keywords: | Loess Plateau soil and water loss effect prediction model. |
