The sampling adopts a Landscape-Shape-Index-based method[21]recommended by the project，and the specific operation is completed on the project platform[22].Considering the complexity of this region，95%confidence level was selected for sampling.At this level，801validation points are extracted（Figure 1，Table 2）.Figure 1 shows that the sampling density is relatively small in the vast area above the plateau，while in the southern fringe area，the ground heterogeneity is strong and the sampling density is high.
