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

Through rainfall simulating in laboratory

and observation on soil sample slices

this study intended to disclose crust development

and reveal the relationship between crust and splash erosion. Two kinds of crust

i.e.

structural crust and depositional crust

were observed in the experiment. With the development of crust

bigger aggregates and grains were dispersed

and bigger pores formed beneath the crust. The development of crust was also the process of soil resisting splash erosion enhanced.
