20世纪60年代以来黄土高原小流域泥沙来源的方法与历史侵蚀过程研究进展

摘要

A small watershed was the basic unit of the laws soil erosion and comprehensive measures which played a critical role in the loess plateau.Reviewed the sources and history of erosion process on the loess plateau watershed sediment, and sum-marized the loess plateau watershed sediment sources and history of erosion process research progress since 1960s.Sediment sources in small watershed mainly from the traditional method, elements tracer method and REE tracer method were analyzed, the prospect of the future development of the small watershed sediment source and sediment erosion research, provided an important reference for the small watershed water and soil conservation, and the scientific evaluation on water and soil resources.%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。
