Abstract:A study was carried out using the method of indoor simulated rainfall combined with geostatistical analysis to investigate characteristics of the change in surface micro-relief under four different kinds of management during the course of sheet erosion and inter-rill erosion. Results show that under the effect of rainfall, regardless of intensity, the surface micro-relieves of slopelands, regardless of management pattern, all demonstrated a certain extent of irregularity and inter-grade transfer in elevation in the process of sheet erosion and inter-rill erosion. GradeⅠ and GradeⅡ were dominated with moving-out, and only a little was transferred back into Grade Ⅰand GradeⅡ even after the inter-rill erosion phase. Little elevation of the surface micro-relief of Grade III moved out, but instead, most of the elevations of other grades moved into Grade Ⅲ, suggesting that in the regions between 0~0.01 m and 0.01~0.03 m deposition of silts occurs readily during the process of sheet erosion and inter-rill erosion.
