Abstract:: Owing to the extremely poor soil cover and fragmentized terrain and physiognomy, the geological environment in the karst region of southwestern China is extremely fragile. It is necessary for ecological rehabilitation to achieve ecological, economic and social sustainable development through social investment. Taking Maotiao River watershed as a case study, with water, governance territory, afforestation as the core, combined biological, engineering, technical measures, the area and spatial distribution of different ecological rehabilitation were achieved through inquiring about the soil erosion and social-economic condition with a GIS environment in the study area. The total area with control measures amounts to 98 232 hm², acounting for 31.52% of the study area. Among the total area with control measures, closing hillside for erosion conservation accounts for 28.1%, afforestation on barren mountains accounts for 16.4%, farmland returning to forest and grassland accounts for 6.78%, and slope cultivated land with 6°～25° accounts for 48.72%. In addition, the cost and benefit of ecological rehabilitation were analyzed. This paper provides a scientific basis for ecological rehabilitation and sustainable use of land resource of the study area.
