| 摘 要： | 采用人工模拟降雨试验法对黄土裸坡降雨产流过程进行了研究。结果表明:(1)坡面径流强度随降雨过程的变化可用对数相关方程进行描述,10~15min是径流强度随降雨过程变化的转折点;(2)坡度对坡面径流深的影响可用抛物线相关方程进行描述,25°左右是径流深随坡度变化的转折点;(3)坡长对坡面径流深的影响可用对数相关方程进行表述,80cm是径流深随坡长变化的转折点;(4)雨强对径流深的影响可用线性相关方程进行描述,雨强与坡度2个因子共同作用时,坡度的作用几乎完全被雨强所掩盖;(5)坡度、坡长及降雨强度对坡面径流深的综合影响可用多元线性相关方程进行描述,其中,降雨强度对坡面径流深的影响远大于坡长及坡度因子。
