Wind-Preconditioned Water Erosion on Typical Aeolian Sandy Soil

The data is derived from simulated wind-water erosion experiments conducted on typical aeolian sandy soil. The experimental design incorporates three key variables: preceding wind speed (0, 7, 9, 11 m/s), rainfall intensity (60, 90, 120 mm/h), and slope (10°, 15°). Based on experimental observations, hydrodynamic parameters including unit runoff power and shear force were calculated, alongside the enrichment ratio and mean weight diameter to characterize sediment sorting and transport. These metrics are utilized to reveal soil loss mechanisms under varying erosive dynamic conditions.

本数据集源于针对典型风沙土开展的风-水侵蚀耦合模拟试验。试验设计设置了三个核心调控变量：先期风速（0、7、9、11 m/s）、降雨强度（60、90、120 mm/h）与坡度（10°、15°）。基于试验观测结果，研究人员计算得到单位径流功率、剪切力等水动力学参数，同时提取了表征泥沙分选与输运特征的富集比与平均重量直径。上述指标被用于揭示不同侵蚀动力条件下的土壤侵蚀机理。
