| Abstract: | Investigation of ecological environment problem is the basis of programming ecological function protected areas. The article mainly introduced the method of using 1∶250 000 TM satellite remote sensing images to find out soil erosion types and intensity in Qinling Mountain of Shaanxi, and drew the conclusion that within the region with the drop of altitude waterpower erosion gradually increased while freeze erosion gradually weakened. The main factor influencing soil erosion is anthropogenic activities. Soil erosion areas in the region increase due to largely exploration and using of forest resources and soil erosion intensity increased because of increase of farmland and slope farmland areas. The work proved that using remote sensing technology combined with GIS technology is useful to investigate and analyse ecological environment problems in process of programming ecological function protected areas. |
