QuickBird remote sensing image and DEM wereused for dataorigin in thisstudy. Soilerosion in- tensity in Baode mining area was assessed by three factors of vegetation coverage, farmland in slope and slope selected as assessing indices. GIS and remote sensing technology were employed in this study. The space distribution of soil erosion intensity in different degree and reason of this distribution were also showed in this paper.
