Assessment Dataset of Windbreak and Sand-fixation Capacity of Ecosystems in the Three-North Shelterbelt Project (2000-2023)

To scientifically assess soil wind erosion and the sand-fixation capacity in the Three-North Shelterbelt Program region, this study adopted the Revised Wind Erosion Equation (RWEQ) to quantitatively estimate soil wind erosion modulus and sand retention based on multi-source remote sensing data and ground monitoring data. A long-term dataset (2001–2023) reflecting the windbreak and sand-fixation capacity of the Three-North Shelterbelt Program region was established.

With a spatial resolution of 250 meters, this dataset covers 13 provinces, autonomous regions and municipalities within the program area, and can be directly applied to dynamic monitoring of wind-sand disasters and comprehensive evaluation of ecological benefits.
