Abstract： In the slope-gully system in the Loess region of hills and gullies,erosion types and shapes are arrayed regularly in the vertical direction,which forms the characteristic of vertical distribution diversity of the erosion types.Based on the artificially simulated rainfall experiment,sheet erosion and rill erosion in the slope-gully system,the dissimilarities and relations among the hydraulic and sediment parameters and the dynamic criticalities at which various types of erosion happen,are studied preliminarily in this paper,which is of great significance to discovering the rules of soil erosion and forecasting the sediment production.
