Abstract: In order to obtain monitoring data of rocky desertification in Leye county in 2011,this paper used the remote sensing image and the data of rocky desertification collected in 2005 for field survey.We analyzed the dynamic changes of rocky desertification in the Leye county and couducted the zonation of the changes.Through the analysis and contrast,the area of rocky desertification was reduced by 5337.0hm².The area transformed from rocky desertification to potential rocky desertification was 6909.5hm²,which was a dominant factor in the process of dynamic changes.The rocky desertification has shown a decreasing tendency.

Key words: rocky desertification, dynamic change, analysis, Leye county
