Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...
