Abstract: The land slope cluster data of the eco-region of the Roof of the World (ROTWSLC) is the basic for ecosystem analysis of the region. It was derived from ASTER GDEM 2 with the cluster models in slope degree and slope percentage. 7 clusters of the land slope according to the degree and 6 clusters according the percentage were identified. The statistics of each cluster had been calculated. The data indicates that the total area of land which slope was equal and higher than 7º was 72.02% of the region and the area of land which slope was equal and higher than 10% was 77.05% of the region. The data in raster were break down into 475 tiles of each of two groups of clusters by 1º x 1º.

Key words: land slope, cluster, Qinghai-Tibet Plateau, Roof of the World, eco-region
