以土槽模拟自然坡面，在人工降雨条件下，对黑土坡面径流参数进行了分析。结果表明：随着降雨强度（简称“雨强”）和坡度的增大，黑土坡面径流的初始产流时间缩短，径流量和径流系数增加。在前期降雨条件下，二次降雨所表现的径流侵蚀特征均强于首次降雨。黑土坡面产生细沟的时间随坡度增大而缩短，当坡度＞15°时，细沟产生时间基本一致，细沟的数量及长、宽、深等参数增大，坡度对沉积的影响作用大于降雨强度。

Runoff parameters of black soil slope were analyzed depending on artificial rainfall simulation experiment .The results show that on black soil slope,initial runoff production time was shortened,and runoff amount and runoff coefficient were increased as rainfall intensity and slope increased .On pre-rain-fall conditions,runoff erosion characteristics of the second rainfall were stronger than the first rainfall . The time of rill forming was shortened as slope increased .When the slope was increased to 1 5°,rill gen-erated at approximately the same time,amount,length,width and depth of rill were increased along with the increase of slope,and the effect of slope gradient on deposition was greater than rainfall intensity .
