Taking the energy and heavy chemical industry area along the boundary of the Loess Plateau and the Maowusu Sandland as study area and the ETM data as main data source, we identified the land use types by GPS, measured the vegetation cover using quadrat method，and analyzed remote sensing and GIS spatial information. The effects of soil erosion factors were determined，and soil erosion map of the area was made.Based on the above results，the erosion types and area of the north of the six counties(districts) of Yulin region were investigated，and the spatial distribution of soil erosion type, intensity and the characteristics were analyzed.
