黄土高原土壤侵蚀(水蚀)多尺度过程与水土保持研究进展

从产生土壤侵蚀机理出发, 分别阐述了黄土高原地区的坡面、 沟谷、 小流域、 流域尺度上的土壤侵蚀(水蚀)研究现状与取得的进展.结合平凉城南侧泾河一级支沟的纸坊沟小流域治理实践和调查, 总结黄土高原地区水土流失治理和水保措施实施的经验及其存在的不足. 建议未来的研究向着"规划性"、 "综合性"、 "量化尺度性"、 "弱化尺度性"模型的研究方向发展, 这对提高地区水土保持质量、 改善水土流失治理现状、 实现水保效益最大化目标具有重要意义.

Progress in Studying Multi-Scale Process of Soil Erosion(Water Erosion) and Soil Conservation in the Loess Plateau

Based on the mechanisms of soil erosion, the development and progress of studying soil erosion (water erosion) in the Loess Plateau are introduced with slope scale, gully scale, small watershed scale and watershed scale, respectively. The experiences and insufficiency in soil loss control, as well as water conservation, are summarized, combining with the manage practice and investigation in the Zhifanggou catchment, a small basin of the first branch of the Jinghe River in the southern margin of Pingliang Municipality. A recommendation of "planning", "comprehensive", "quantitative measuring" and "weakened measuring" is put forward for well developing the research in future. These will be of great importance for improving soil conservation quality, improving soil erosion status and for achieving the maximization of soil conservation benefits.
