摘要
坡面是土壤侵蚀最基本的地貌单元 ,定量研究坡面侵蚀能为研究土壤侵蚀规律、确定坡面重点侵蚀部位、建立土壤侵蚀预报模型提供科学依据。总结了溅蚀、片蚀、细沟侵蚀、浅沟侵蚀的定量研究进展 ,简述了土壤侵蚀模型的研究进展 。
The hillslope is the most preliminary unit in study on soil erosion. To study soil erosion quantitatively on the hillslope can offer the scientific evidence for studying soil erosion rule, confirming the focal point control location on the hillslope and forming soil erosion prediction model. The progress in the study on detachment erosion, sheet erosion, rill erosion and shallow gully erosion is discussed in detail, the progress in the soil erosion prediction model is also introduced briefly. The other methods applied to study soil erosion, like remote sensing, laser technology, natural radionuclides tracers, are reviewed.
