In order to determine the micro topography fractal characteristics of rainfall erosion on sloping lands of the loess area,this paperused the slope surface soil of gullied rolling loess area as a sample,set up four kinds of farming pattern,five grade levels and observed theerosion of the tiny terrain data by indoor artificial rainfall tests.R/ Sanalysis method of rainfall erosion of tiny terrain was analyzed and theHurst index was determined. The results show that under the conditions of different cultivatio...
