小流域作为黄土高原水土流失综合治理的基本单元,赋存了大量的泥沙侵蚀特征和侵蚀环境变化信息。它在减少黄土高原土壤侵蚀方面发挥着十分重要作用。概述了20世纪60年代以来黄土高原小流域泥沙来源和历史侵蚀过程方面的研究进展,小流域泥沙来源主要从传统方法、元素示踪法及REE稀土元素示踪法方面进行了分析,展望了未来小流域泥沙来源及泥沙侵蚀研究的发展,为小流域开展水土保持工作、对水土资源进行科学的评价和开展更深入的研究提供了重要参考。
Small watershed, as the basic unit of comprehensive management of soil and water loss in the Loess Plateau, contains a large amount of information on sediment erosion characteristics and erosion environment changes. It plays a very important role in reducing soil erosion in the Loess Plateau. The research progress of sediment source and history erosion in the small watershed of the Loess Plateau since 1960s are summarized. The sediment sources of the small watershed are mainly analyzed from the traditional methods, the element tracing method and the REE trace element tracing method, and the prospect The development of research on sediment source and sediment erosion in small watershed in the future provides an important reference for carrying out soil and water conservation work in small watershed, making a scientific evaluation of soil and water resources and carrying out more in-depth research.
