1.
The results indicated that the REE tracer technology has high precision to quantify the spatial-temporal process of soil erosion; In earlier rainfall course, the development degree of sheet and rill erosion was general equation; Other.
结果表明:REE示踪技术对定量研究土壤侵蚀具有较高的精度;降雨前期,片蚀与细沟侵蚀发育程度基本相当;后期细沟侵蚀占据坡面侵蚀的主导地位,其侵蚀平均加速度和平均侵蚀率分别是片蚀的15倍、9倍;试验结束,细沟侵蚀占据坡面总侵蚀的90%;本试验条件下,坡面下1/3区域为侵蚀活跃带。
