系统梳理了西南喀斯特二元结构下土壤流失的研究进展,结果表明喀斯特山区土壤侵蚀研究总体起步晚,基础研究落后,已有研究成果多集中在地表侵蚀现状、成因、治理措施等方面。喀斯特二元结构背景下存在地下土壤流失的观点已经得到多数学者的认可,然而受限于研究技术方法 ,缺乏观测数据,地下流失途径、流失量及其危害仍不清楚。因此,寻求必要的技术手段,从流失途径和过程开展野外观测是今后喀斯特二元结构下土壤流失研究的重点。
The results show that the research of soil erosion in Karst mountains started late and the basic research lags behind. The existing research results mostly focus on the status quo, causes and measures of surface erosion. The viewpoint that underground soil loss exists under the dual structure of karst has been approved by most scholars. However, it is still not clear whether it is limited by the technical methods of research, the lack of observation data, the way of underground loss, the amount of loss and its damage. Therefore, seeking the necessary technical means to carry out field observation through the lost path and process is the focus of the future research on soil erosion under the dual karst structure.
