Abstract: Desertification is a developing process of desert-like landscape manifesting itself by land degradation resulted mainly from climatic variations and human activities, In the dry-hot valley in Yuanmou, Yunnan Province,the land has such desert-like landscapes as badland topography, sandy desertification and thorny succulent shrubs with characteristics of tropicaldesert vegetation, Except for several small basins where the terrain slopes are gently,the degraded area is 1006.02 km2.The degraded land accounts for 70.15%of total area of Yuanmou dry－hot valley(including Slightly degraded land which is 12.65%, the moderately degraded land which is 48.38%and the severely degraded land which is 30.77%).After discussion on the status, genesis and hazard of land degradation, the control strategies are finallyproposed in this paper.
