摘要

通过室内模拟实验对降雨侵蚀条件下流域地貌变化过程进行了研究，研究表明，单位降雨量所产生的流域表面面积、沟道投影面积和流域体积的变化量在整个流域发育过程中呈现出一定规律性，沟道投影面积和流域体积均表现为先逐渐增加，达到一定程度后又逐渐下降，而表面面积则表现为先逐渐增加，达到一定程度后则处于上下波动的状态。

Abstract

Process of watershed topography variation by rain erosion was studied with indoor simulating experiment. The result shows that watershed surface area

channel projected area and watershed volume per precipitation varies regularly. Channel projected area and watershed volume increase firstly

and decrease after reached definite degree. But surface area increases firstly

then fluctuant state after reaches definite degree.
