黄土高原坡面降雨产流产沙过程变化的统计分析

Statistic Analysis on Variation of Rainfall and Runoff-sediment Yeild Process on Slope Surface in Loess Plateau Region

该文根据子洲团山沟３号径流场（坡度２２°，面积６０ｍ×１５ｍ＝３００ｍ＾２）３３次降雨产流产沙的过程变化情况，统计分析了不同类型降雨坡面产流过程中的降雨变化及产流产沙过程变化。

Based on the information of 33 times rainfall,runoff and sediment yield at No 3runoff plot in Zizhou Tuanshangou watershed,the variation of rainfall and runoff-sediment yieldon slope surface under diffrent rain pattern are analyzed by using statistic method。
