Spatiotemporal dynamics and drivers of wind erosion on the Qinghai-Tibet Plateau, China

Land degradation caused by wind erosion seriously threatens the supply of ecosystem services on the Qinghai-Tibet Plateau (QTP). Assessing wind erosion variations is critical to identify key change areas and formulate desertification control strategies. In this study, we evaluated the spatiotemporal...
