通过人工模拟降雨溅蚀实验,测定土壤溅蚀速率,同时采样制作土壤切片,观察分析结皮的发育特征以及与土壤溅蚀的关系。结果表明,降雨过程中有两种类型结皮形成,即沉积结皮和结构结皮。土壤结皮随着土壤表面大团聚体或者大颗粒的分散而形成,并且伴随着下层大孔隙的出现。土表结皮的完善过程,也是土壤抗溅蚀能力增强的过程 Soil erosion rate was measured by artificial simulated rainfall erosive test. Simultaneously, soil samples were made by sampling. The development characteristics of crusts and the relationship with soil erosion were observed and analyzed. The results show that during the rainfall there are two types of crust formation, that is, the deposition of crusts and structural crusts. Soil crust is formed by the dispersion of large aggregates or large particles on the surface of the soil and is accompanied by the appearance of macropores in the lower layer. The perfect process of soil crust, but also the ability of soil anti-corrosion enhanced
