According to the topography characteristics of Yenisei River Basin，a total of 10 elevation clusters were developed（Table 2）.In order to reflect the distribution characteristics of low-altitude areas，elevation less than500 m was divided into four intervals.The elevation more than 3，000 m was divided as a single interval.The rest elevation from 500 m to 3，000 m was divided by an interval of 500 m.The Elevation Cluster Dataset Covering the Yenisei River Basin shows that the lowland area lower than 500 m is1.65×105 km2，accounting 6.21%of the basin area；the area with elevation from50 to 100 m is 9.93×104 km2 accounting 3.74%of the basin area；the land with elevation between 100 m and 200m is 1.71×105 km2，about 6.43%of the total area of the basin.In Yenisei River Basin，the main part with area 9.75×105km2 locates between 200 m and 500 m，which accounts about 36.66%of the basin；the land with elevation between500 m and 1，000 m is 5.70×105 km2，12.27%of total area of the basin.The mountain land more than 1，500 m above sea level accounts 13.26%of the basin area.The dataset was archived as.tif file with 112 MB compressed data size.The Elevation Cluster Dataset Covering the Yenisei River Basin is shown in Figure 4，and the statistics value is shown in Table 2.
