| Abstract: | The study area was chosen in Yijinholo County, Mu Us Sandland, by means of ridge estimation method. The factors affecting biomass were optimized and filtrated according to the orientation investigation data in field and the corresponding RS and G1S information. The main factors were found out, the biomass estimation model are set up, and the quantitative estimation of regional biomass and automation of cartography were fulfilled, which provides the scientific base to establish regional development plan and desertification combating plan. |
