摘要

在高强度人工降雨条件下

作者研究了地面坡度、植被覆盖度、降雨强度对土壤入渗速率的影响。结果表明:累积入渗量与坡度成反比;影响累积径流深的临界坡度明显存在。且在本试验条件下

不同时段、不同植被类型的临界坡度在24°～30°之间变化;植被覆盖度增加

累积入渗量呈指数增加

随着降雨强度增大

土壤的稳定入渗率有增大的趋势。

Abstract

The author studied the effects of slope gradient of land surface

vegetation coverpercentage

rainfall intensity upon infiltration rate into soil under the conditionsof artificial rainfall with high intensity. The results showed that the accumulatedinfiltration water was in inverse proportion to slope gradient

and also

there exist-ed an apparent critical slope gradient affectimg the depth of accumulated runoffwater. In the case of this test

the critical slope gradient of different time sectionsand different vegetation

types varied between 23.6°-30.4°. The vegetation coverpercentage increased

and the accumulated infiltration water went up exponentiallyThe steady infiltration rate has an increasent trend with the increasing rain intenasity.
