摘要: 本文利用野外调查和形态测量资料划分黄河中游黄土丘陵地区的沟谷类型,分析各类沟谷发生发展过程中的相互关系,以揭露这个地区侵蚀沟发育的规律,为防止它的发展提供理论依据。

Abstract: Taking the evolution processes of gully and morphological features as the fundamentals of classification and major standard to distinguish the processes, the author has divided the erosive gullies in the Loess hilly region in the middle reaches of Yellow River into the Shallowgully, Cut-gully, Gully Golch and Valley which present the model of gully evolution processes in the Loess region. The various morphological parameters of a group of gullies are obviously and concentrically distributed in a certain area, and the Critical values are existed. There is a good correlation between the morphologic parameters of same group of gullies as well as between the same one or two parameters of various kind of gullies. To diffuse slope runoof, stabilize and rise up erosion base are the main approach to prevent the erosion gullies from developing.
