    Research progress on soil erosion mechanism and ecological restoration technology in feldspathic sandstone region

    • 摘要: 黄河流域的生态保护和高质量发展,是我国新时代生态文明建设的重要内容。砒砂岩区是黄河流域水土流失最严重的区域之一,也是黄河粗泥沙的集中来源区。砒砂岩区水土流失治理和生态修复工作倍受重视,多年不懈的水土保持工作取得了巨大成就,水土流失防治成效显著,生态环境明显好转,但砒砂岩区的水土流失形式仍旧严峻,生态环境依然脆弱,治理质量还有较大提升空间,大面积的人工林也面临着退化风险和更新难题。砒砂岩区土壤侵蚀机理研究成果丰富,但该区水文下垫面复杂多变,侵蚀类型多样复合,前人的研究仍沿用黄土高原区的理论与方法,极大的限制了砒砂岩区土壤侵蚀机理研究的发展。本文结合前人的研究成果和作者的科研经验,概括了砒砂岩区土壤侵蚀机理与生态修复技术研究的发展历史,从基岩侵蚀内因、土壤侵蚀机理研究、生态修复技术研究、存在问题与发展方向4个角度,对砒砂岩土壤侵蚀机理研究和生态修复技术工作的成果进行系统梳理,剖析现有研究的不足之处,指出未来砒砂岩区土壤侵蚀机理研究和生态修复技术发展发向。

       

      Abstract: The ecological protection and high-quality development of the Yellow River Basin are important for the construction of ecological civilization in the new era of China. The feldspathic sandstone region is one of the regions facing the most serious water erosion in the Yellow River Basin. It is also the coarse sand source area of the Yellow River. Great attention was paid to the soil and water erosion control and ecological restoration in feldspathic sandstone region. After persistent efforts through soil and water conservation for years, great achievements had been made, the effect of soil and water erosion control was remarkable and the regional ecological environment was gradually recovering, but the situation of soil erosion in the feldspathic sandstone region remained grim, the ecological environment is still weak in the feldspathic sandstone region. The plantations face the enormous risk of degradation and regeneration of plantation. There are plenty of literatures about the research of soil erosion mechanism of the feldspathic sandstone region. However, the hydrographic underlying surface of this region is complicated and the soil erosion types are diversified. It cannot meet the requirements of development of soil erosion mechanism of feldspathic sandstone region to continue using traditional methods of loess area. This article presents the history of the study on soil erosion mechanism and ecological restoration technology in feldspathic sandstone region, combining the previous research results and the author’s scientific research experiences. Systematic analysis was done on the progresses and shortcomings in the study on soil erosion mechanism and ecological restoration technology from the aspects of internal cause of the erosion in bed rock, soil erosion mechanism, ecological restoration technology, existing problems and development direction. Five directions for future researches on soil erosion mechanism and ecological restoration technology in feldspathic sandstone region were given.
