侵蚀过程中地表糙度变化特征的研究
摘要
在地表侵蚀过程特征的基础上
通过室内人工模拟降雨试验
运用三段降雨法
研究了这一 过程中地表糙度的变化
得出:降雨过程中
随机糙度的地表与有向糙度的地表变化不同
前者呈增加趋势;而后者呈递成趋势
且随着雨强的增加
变化幅度增大.
Abstract
On the base of the surface erosion and indoor artificial rainfall
the variation of the characteristics about soil surface were studied by the methods of three stages rainfall. The result was that the variation of random roughness and oriented roughness were different. The former had an increasing trend and a decreasing trend for the latter
and the variation increased with the increasing rainfall density.
