摘要:
基于土壤侵蚀REE示踪法的技术需要，对全坡长小区细沟侵蚀垂直分布特征进行了分析研究。在野外实地量测的基础上．首先提出了表征细沟侵蚀形态，强度的三个参数，即细沟平面密度（μ）细沟平均深度（H）及细沟侵蚀强度（EI），并对上述参数垂直变化特征进行了分析、计算，最后分析了全坡长小区细沟相对侵蚀量在垂直方向上的变化，初步得出细沟侵蚀强烈地段在坡面的中下部位．约占被面细沟侵蚀总量的70%以上。
Abstract:
Based on the need of soil erosion rare earth element (REE) tracer method, the rill erosion spatial characteristic was researched on the field plot. At first, we give three parameter to show the rill erosion intensity and its shape, that is rill horizon density (μ) 、 rill average depth (H) and rill intensity (EI),then we calculated the all parameters. Finally, we researched the relationship between the related erosion yield with the slope length. The results showed that the serious position of rill erosion is on the middle and down of slope. It is about 70 % of totaIl rill erosion yield.
