摘要

以天然降雨侵蚀特征为依据

在室内研究了坡耕地土壤结皮的形成特征。通过对结皮坚实度、容重和厚度的测定发现

在结皮的形成过程中

降雨以打击夯实作用为主

径流以淤积压实作用占主导地位

且随雨强、径流深度的增加

这种作用也愈加显著 ;但随坡度增大

两者的作用受到了抑制

使结皮形成的完善程度降低。总体来看

降雨的作用要大于径流作用

Abstract

Based on natural rainfall erosion characteristic

the paper studied on soil crust formation on the slope farmland according to rainfall

runoff and rainfall runoff slope comprehensive methods in indoor. Some characteristics are found through measuring the crust hardness

bulk density and thickness of crust layer. In the process of soil crust forming

rainfall function is mainly impact

runoff function is mainly depositing and condensing

and their functions increase as rainfall intensity and depth of runoff increasing. But the function is also limited while slope degree increasing

the growth of crust is no good. On the whole

the function of rainfall is more powerful than runoff.
