Abstract：
The Yalu River rises in southern slope of Tianchi Lake of Mt. Changbai at 2745m and meets the Yellow Sea at the West Korea Bay at 0 m. The total area of the Yalu River basin is 65215.49 km². Based on the DEM data, 8 elevation Clusters were identified and calculated. The statistic results of elevation clusters are: area, which elevation is less than 50m, is 1926.22 km²，2.95% of the total area；the area, which elevation is between 50-100m, is1327.35 km², 2.04% of the total area；the area, which elevation is between 100-200m, is 3141.77 km², 4.82% of the total area；the area, which elevation is between 200-500m, is 15987.50 km², 24.51% of the total area；the area, which elevation is between 500-1000m, is 23492.12 km², 36.02% of the total area；the area, which elevation is between 1000-1500m, is 13868.31 km², 21.27% of the total area；the area, which elevation is between 1500-2000m, is 5102.53 km², 7.82% of the total area；the area, which elevation is higher than 2000m, is 369.69 km², 0.57% of the total area. That means more than 80% of the land in Yalu River Basin is located at 200-1500m; while, only 5% of the land is lower than 100m. The dataset is archived in.adf data format with the data size of 3.72 MB (2 MB in compress).
