花岗岩红壤丘陵区崩岗侵蚀与典型切沟侵蚀的异同点探析OA北大核心CSTPCD

Analysis of Similarities and Differences Between Benggang Erosion in Granitic Red Soil Hilly Area and Typical Gully Erosion

中文摘要英文摘要

崩岗侵蚀与切沟侵蚀威胁区域生态安全,是当前土壤侵蚀研究领域所关注的热点和难点,二者存在着共性和个性,但能否将切沟侵蚀防治方法应用于崩岗侵蚀区尚不明确.本文从气候、母质和土壤、地形、植被方面对比了影响崩岗侵蚀和切沟侵蚀的环境因素.结合崩岗侵蚀与切沟侵蚀外观形态的表现形式,阐述二者发育过程和侵蚀发生的动力机制.通过综合分析,崩岗的侵蚀物质和侵蚀形式具有独特性,在防控措施的布设方面需考虑更多因素的相互作用.在此基础上,提出崩岗发育机制、防治措施及构建侵蚀模型等有待深入研究的问题.

The Benggang erosion and gully erosion threaten the regional ecological security,which are the hot and difficult points in the field of soil erosion research,however,it is not clear whether the control methods of gully erosion can be applied to Benggang erosion area.In this paper,the environmental factors affecting gully erosion and Benggang erosion were compared from the aspects of climate,parent material,soil,topography and vegetation.Combined with the appearance forms of Benggang erosion and gully erosion,the development process and the dynamic mechanism of erosion were expounded.Through comprehensive analysis,the erosive substance and erosive form of Benggang erosion are unique,and the interplay of more factors should be considered in the layout of control measures.On this basis,the development mechanism of Benggang erosion,the prevention and control measures and the establishment of erosion model are put forward.
