  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 nil erosion was general equation ; otherwise in the following course, the rill erosion was dominant in the total erosion, its average erosion acceleration and the average erosion rate was 15 and 9 times of sheet erosion, respectively ; in the end of experiment, the rill erosion took up 90 % of total erosion amount ; the section of slope bottom occupying about 1 / 3 slope area was active erosion segment in this experiment

    結果表明： ree示蹤技術對定量研究土壤侵蝕具有較高的精度；降雨前期，片蝕與細溝侵蝕發育程度基本相當；後期細溝侵蝕占據坡面侵蝕的主導地位，其侵蝕平均加速度和平均侵蝕率分別是片蝕的15倍、 9倍；試驗結束，細溝侵蝕占據坡面總侵蝕的90 % ；本試驗條件下，坡面下1 / 3區域為侵蝕活躍帶。
