西南喀斯特二元结构下土壤流失研究进展(英文)

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。

Research Progress of Soil Loss in Karst Areas under the Dual Structure of Southwest China

The research progress of soil loss under the dual structure of southwest karst is systematically studied. The results show that the research of the soil erosion in karst mountainous area started late, and the basic research is lagging. Most of the existing research results focus on the present situation, causes and control measures of surface erosion. The view of underground soil loss in the context of karst diploid structure has been recognized by most scholars. However, limited to the research methods and the lack of observational data, the way of underground soil loss, the amount of loss and its harm are still unclear. Therefore, seeking the necessary technical means to carry out the necessary field observation from the way and process of loss is the focus of the study of soil loss under karst structure in the future.
