岩质边坡植被抗冲刷现场试验研究

阐述了岩质边坡生态防护植被现场抗冲刷试验的试验目的,详细介绍了其试验方案及现场试验方法。通过对试验区草种生长情况的评判,对试验区草种抗冲刷能力的测试,对适宜广西寨任路边坡防护的草种进行了比选,对不同草种抗冲刷能力进行了探讨。通过对试验数据的分析,得到了不同草种在不同降雨强度下与边坡冲刷的关系,为岩质边坡生态防护植被的选择提供了依据。

In-situ Washing-out Tests of Ecological Protection of Rocky Slopes

Following objective statement of the study on in-situ washing-out testing of ecological protec?tion of rocky slopes, the test scheme and method are detailed in this paper. Through judging, testing, and comparison between washing-out resistances of different types of grass, selection was made for the slope on Liuzhai-Shuiren Highway in Guangxi. Analyses on the test data resulted in the relationship between rainfall intensity and erosion extent for various types of grass, which provides a basis of the plant selection for ecologi?cal protection of rocky slopes.
