摘  要:
采用活动式人工模拟降雨试验装置,在室外对不同种类土壤、坡比、植被条件下的模型坡面产流进行了试验研究,重点分析了下垫面因子对坡面流流速的影响。结果表明:细沟流速随坡度的变陡而明显增大,坡面流速和细沟流速的比值随坡度的增加有明显变小的趋势,土壤理化性质、地表糙率的不同使坡面产流等也呈现出不同的特点。

摘  要:
The authors adopts movable artificial rainfall test devices to conduct experimental study on model slope yields under the outdoor conditions of different type of soil, slopes and vegetation and puts the stress on the analysis of impacts of underlying surface factor to the velocity of slope yields. The results show that the rill velocity is notably faster as slope getting deeper, the specific value of slope velocity and rill velocity is getting notably smaller along with the increase of slope and the difference of physical chemistry of soil texture and land surface roughness coefficient causes different slope yields.
