利用稀土元素示踪技术及土槽径流冲刷试验 ,系统研究了不同坡度、不同流量下各断面的土壤剥蚀率和水流剪切力之间的关系。试验结果表明 ,土壤剥蚀率随着水流剪切力的增加其对数呈线性关系
The relationship between soil erosion rate and water flow shear force was systematically studied using rare earth element tracing technique and soil runoff scouring test. The results show that the soil erosion rate increases linearly with the increase of shear force
