摘要
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 。
Based on runoff scouring experiments by means of flume soil and rare earth elements tracer method, the relationship of soil detachment rate and flow shear stress during different stages under different slope gradients and runoff discharges was researched. The results showed that soil detachment rate increased with the increase of flow shear stress, their logarithm was linear.
