摘要:
东北黑土漫岗区侵蚀沟发育广泛，侵蚀沟的发展已经严重影响了该区工农业生产的发展。根据东北黑土漫岗区侵蚀沟的发展阶段、形态特征、侵蚀沟底冲淤状况、侵蚀沟边坡扩展方式等，将该区侵蚀沟分为顺犁沟、浅沟、切沟、冲沟和槽沟5种类型。在此基础上，对侵蚀沟由顺犁沟发展至槽沟的发展过程、发展条件，以及面蚀与沟蚀的发展转化关系进行了阐述。最后，从宏观和微观两个方面阐述了侵蚀沟在东北黑土漫岗区的分布特征。
Abstract:
The developments of industry and agriculture have been badly restricted for the severe gully erosion in the gentle hilly black soil regions in Northeast China.The erosion gully can be classified into 5 types according to the erosion stage, the gully shape, the state of erosion or sedimentation in gully bottom, the erosion type along the gully edge, and so on.On the base, the gully erosion process, the gully erosion developing condition and the interactivity between sheet erosion and gully erosion have been described.In the end, the spatial distribution characteristics of erosion gully in the gentle hilly black soil regions in Northeast China were formulated at macroscopic view and microscopic view.
