溯源侵蚀 retrogressive erosion
[地理] headward erosion
- 本文阐述了溯源淤积和侵蚀基准面的概念。
This paper dwells the concepts of retrogressive aggradation and the datum of erosion. - 形成机制是流水溯源侵蚀—岩石块体崩塌—谷坡后退。
The formation mechanism is the flowing water trace to the source erosion-rock collapse-ancient slope withdrawal. - 最后还探讨了洞穴侵蚀与其它侵蚀方式之间的相互联系与作用,对沟谷溯源侵蚀的发生机理提出了新的认识和建议。
The new understanding on gully retrogressive erosion was put forward by an approach of relationship between tunnel erosion and other erosion forms.
