In order to analyze the characteristics of soil erosion in different grades of rocky desertification area, taking the typical karst area Guanling County of Guizhou Province as the research object, according to the classification of ‘standard for classification and gradation of soil erosion’ and ‘techniques standard for comprehensive control of soil erosion and water loss in karst region’, we used ZY-3 remote image as the data source, made the soil erosion and rocky desertification map in Guanling County in 2015 by comprehensive using the ‘3S’ technology. We analyzed the characteristics of soil erosion in different rocky desertification areas. The results showed that the characteristics of soil erosion in different grades of rocky desertification areas in Guanling county had certain regularity, soil and water loss rate of GuanLing karst area was 9.4% lower than in non-karst area, and soil and water loss rate in non-rocky desertification area was slightly lower than rocky desertification area, high grade rocky desertification area was lower than low grade rocky desertification area also. The regional distribution and intensity of rocky desertification and soil erosion in Guanling County were not consistent. In the process of comprehensive control of soil erosion, Guanling County should strengthen the management of lower level rocky desertification area, at the same time, it is necessary to strengthen the prevention of soil erosion in non-rocky desertification area.
