摘要
本文通过淳化县泥河沟等三条沟谷的调查、航片判读和定位观测,分析了渭北高原沟谷侵蚀的主要类型和分布、沟谷发展、侵蚀和输移变化,以及沟谷侵蚀的分带规律,并提出治理方略。
This paper analysed some main erosion patterns and distributions of gully erosion, the development of gully, the changes between erosion and nature load as well as the pattern zonation rules of gully erosion depend- ing on the feild investigation, the airphoto interpretation, and the loca- tion records of Nihegou and other two gullies in Chunhua County.
