Ecosystem service research is essential to identify the contribution of the ecosystem to human welfare. As an important ecological barrier zone, the Kubuqi Desert supports the use of a crucial wind erosion prevention service (WEPS) to improve the ecological environment quality. Based on the Revised Wind Erosion Equation (RWEQ) model, the spatial and temporal changes of WEPS in the Kubuqi Desert region were simulated from 2000 to 2022, and the impacts and interactions of natural and socio-economic factors including numerical and typological variables on the spatial pattern of wind and sand control services in the region were analyzed by using geographical detector. From 2000 to 2022, the total WEPS provided in the Kubuqi Desert ranged from 0.35 × 107 t to 1.26 × 107 t. The average WEPS per unit area was between 0.19 kg m-2 to 0.68 kg m-2.WEPS has a higher spatial distribution in the east and a lower spatial distribution in the west. Soil type was the most important driver of the actual wind erosion (SL), with vegetation cover, elevation, mean annual temperature, mean annual wind speed, and mean annual precipitation as the main drivers, and population size and GDP as secondary drivers. The interaction analysis showed that the interaction of weather factor, vegetation factor and soil factor is the dominant factor influencing the amount of soil wind erosion in the Kubuqi Desert.
生态系统服务研究对于确定生态系统对人类福祉的贡献至关重要。作为重要的生态屏障区，库布齐沙漠提供了关键的防风蚀服务（WEPS）以改善生态环境质量。基于修正风蚀方程（RWEQ）模型，模拟了2000年至2022年库布齐沙漠地区WEPS的时空变化，并利用地理探测器分析了包括数值和类型变量在内的自然和社会经济因素对该地区风沙控制服务空间格局的影响及相互作用。2000年至2022年，库布齐沙漠提供的WEPS总量在0.35×10⁷吨至1.26×10⁷吨之间。单位面积的平均WEPS在0.19千克·米⁻²至0.68千克·米⁻²之间。WEPS在东部的空间分布较高，在西部的空间分布较低。土壤类型是实际风蚀（SL）的最重要驱动因素，植被覆盖度、海拔、年平均气温、年平均风速和年平均降水量是主要驱动因素，人口规模和国内生产总值是次要驱动因素。交互作用分析表明，气象因子、植被因子和土壤因子的交互作用是影响库布齐沙漠土壤风蚀量的主导因素。
