Study of the simultaneous effect of wind and rain is of great importance in the environmental studies of erosion for more accurate measurement and modeling of soil loss. There is little information on the combined effects of rain and wind on soil erosion as well as soil organic carbon (SOC) loss. The purpose of this study was to investigate interrill erosion in relation to SOC loss and enrichment ratio (ER_oc) as influenced by rain intensity and wind velocity linking to flow hydraulic characteristics. Three rain intensities of 20, 40 and 60 mm h⁻¹ and four wind velocities of 0, 6, 9 and 12 m s⁻¹ were generated on three different soil samples (sandy, sandy loam and loam), each at three replicates (totally 108 runs). The SOC loss was determined through the concentration of organic carbon in sediment and the measured sediment load. The values of SOC loss and ER_oc ranged from 0.04 to 4.04 mg m⁻¹ s⁻¹ and from 0.52 to 9.40, respectively. The measured interrill erosion rates and SOC losses increased at higher wind velocities and rain intensities, especially when wind velocity became more than a threshold value of 9 m s⁻¹. For each soil, a direct linear relationship was distinguished between the losses of soil and SOC. Accordingly, SOC loss accounted for 0.36%, 0.17%, and 2.19% of the total soil loss in the sandy, sandy loam and loam soils, respectively. The ER_oc was nearly constant for each soil and not changed with the increased soil erosion rate. Finally, flow velocity and unit stream power were found as the best predictors of soil and SOC losses in a wind-driven interrill erosion system.

为了更准确地测量和模拟土壤流失，研究风雨的同时影响对侵蚀的环境研究非常重要。关于雨和风对土壤侵蚀以及土壤有机碳（SOC）损失的综合影响的信息很少。这项研究的目的是研究与降雨损失和风速相关的，与流水力特性相关的，与SOC损失和富集率（ER _oc）有关的层间侵蚀。三种降雨强度分别为20、40和60 mm h ^-1，四种风速分别为0、6、9和12 m s ^-1在三个不同的土壤样品（沙质，砂壤土和壤土）上生成了三份样本，每份样本进行了三次重复（总共108次）。SOC损失是通过沉积物中有机碳的浓度和测得的沉积物负荷确定的。SOC损失和ER _oc的值分别在0.04至4.04mg m ^-1 s ^-1和0.52至9.40的范围内。在较高的风速和降雨强度下，尤其是当风速超过9 m s ^-1的阈值时，测得的钻探侵蚀速率和SOC损失会增加。对于每种土壤，土壤损失与SOC之间存在直接的线性关系。因此，在沙质，沙质壤土和壤土中，SOC损失分别占总土壤损失的0.36％，0.17％和2.19％。每种土壤的ER _oc几乎不变，并且随着土壤侵蚀速率的增加而没有变化。最后，流速和单位流功率被认为是风驱间蚀系统中土壤和SOC损失的最佳预测指标。
