摘要

坑状浅沟作为浅沟与切沟的中间过程，深入理解它对于进一步认识切沟侵蚀规律具有十分重要的意义，但是还没有见到相关的研究报道。以内蒙古高原的一个小流域为例。利用高精度的全球定位系统（GPS）测量坑状浅沟侵蚀的形态参数，探讨了坑状浅沟的相关特征，分析了坑状浅沟的坡度（S）和上有集水区面积（A）的关系（S—A）、侵蚀体积（V）和长度（L）的关系（V-L），以期能推动坑状浅沟侵蚀的研究。

Abstract

Hole-ephemeral gully is a media process between ephemeral gully and gully.It has very important significance for us to understand in advance the laws of gully erosion.However

little research on hole-ephemeral gullies in prior literatures has been done.A small catchment on the Inner-Mongolian Plateau is regarded as a case study and Global Position System(GPS) is used to measure the morphology parameters of hole-ephemeral gullies and topography of the study area.It discusses relative characteristics of hole-ephemeral gullies and analyzes the relationship(S-A)between slope gradient(S)at gully head and upslope drainage area(A)for hole-ephemeral gullies and the relationship(V-L)between lengths(L) and erosion volumes(V)for hole-ephemeral gullies in order to promote the studies on hole-ephemeral gullies.
