By placing different rare earth oxide in different soil depth and different section across a slope in the field plots
the temporal and spatial process of soil erosion is studied under simulated rainfall situation.The results indicated that there is a dynam ic process from sheet erosion
ripple erosion near the plot bottom
headward erosion
and relative stableness of slope(ended on the erosion basis).Relevant erosion typeswere dominant within corresponding erosion stages.The emergence of rill head is the key factor boosting up the erosion of different section on slope.Under gentle intensity consecutive rainfall
headword erosion is dominant on the plots
and its erosion process is much more stable than erosion process of the first rainfall .
