Abstract The administration areas of the ecological integrated management for the Karst rocky desertification in Huajiang of Guizhou Province was selected as the study area.Based on the comparable analysis on soil physicochemistrical properties,microclimate effects,vegetation quantitative characteristics and surface condition of soil erosion between before and after the desertification control,the results indicate that the rocky desertification may be controlled,and the effects show that the Strong is best,which is better than the other three kinds;Latent is worst.At the same time the soil property,soil fertility,surface vegetation cover rate,the biodiversity and the regional local climate were improved.
