Wind erosion forms one of the main causes of land degradation, especially in arid regions with little or no vegetation. It is important to determine the role of vegetation in wind erosion prevention as an ecosystem service (ES). However, the impact of vegetation dynamics on the transmission pathways of dust is still unclear. Taking the dryland of China as the study area, this study analysed the spatial-temporal variability of wind erosion prevention from 2001 to 2020 by modelling the estimated movement of dust and the suppressive effect of vegetation on dust. The results showed that the annual amount of dust prevented was 2865Tg. The wind erosion prevention was higher in the northeast and lower in the southwest. Over the past two decades, wind erosion prevention increased 13% in 2020 compared with 2000. Increased vegetation cover effectively reduces the risk of wind erosion. In addition to China, 18 countries benefited from vegetation to offset dust. This study shows vegetation's importance in reducing dust transport at a transnational scale.
