Spatial distributions of the relative changes (%) caused by the human footprint for the modeled SOC stock at various soil depths on the Qinghai Plateau. The relative changes (%) were the comparison of the SOC stock estimated by the model that considered human footprint factors (Model_H) and the SOC stock estimated by the model without considering the paleoclimate and human footprint factors (Model_Ori). SOC represents soil organic carbon
