Abstract
GIS technology and fractal theory provide a powerful tools in the soil erosion study.Based on GIS and three-dimensional laser，and under rainfall intensities of 45, 90 and 130mm/h with 20°slope gradient using simulated rainfall experiment, Amount of erosion , fractal dimensions and Hydraulic parameters were studied from different slope positions, Which was up-slope mid-slope and low-slope, The results showed that the distribution of erosion along the slope was difference in different rainfall intensity. the fractal dimensions increased along the slope，It indicated that the complexity of erosion increased with slope length. Reynolds number, Froude number, Darcy-weisbach drag coefficient and the shear stress were the important hydraulic parameters to study the soil erosion process and soil erosion mechanism. They were showed the same or the opposite trend with fractal dimensions, taking into the erosion distribution and erosion development process, Dynamics of soil erosion could be further advance.
