Abstract:: There is the inseparable relationship between rocky desertification phenomenon and water and soil loss. To further analyze the relationship between rocky desertification and water and soil loss, we took rocky desertification and Water and soil loss data of Guizhou Province in 2010 as the base of data interpretation, thus obtained the rocky desertification distribution at different levels of water and soil loss and the distribution of water and soil loss at the different rocky desertification levels. The results show that: Guizhou Province rocky desertification occurs mainly in mild to moderate erosion areas, its incidence is 24.31%, 24.09%, respectively, while the water and soil loss occurs mainly in slightly rocky desertification and potential rocky desertification area, the incidence rate is 35.70%, 34.16%; the level change of water and soil loss or rocky desertification rating does not necessarily render the appropriate level of rocky desertification and water and soil loss grade changes, rocky desertification occurrence and ecological restoration lags.
