摘要

在全球气候变暖和“双碳”战略的背景下，植被护坡成为一种潜在的碳负排放边坡加固和侵蚀控制手段。植被根系的发育可以改变土体结构和水力学特性，进而影响边坡的稳定性。虽然一些试验研究已经探讨了特定条件下植被对土体水力学特性的影响，但是对于植被根系改变土体水力学特性的一般规律尚不清楚。该文从植被蒸腾作用、根系物理作用以及根系生物化学作用3个方面入手，收集并梳理了近年来国内外相关研究，分析并总结了植被根系改变土体水力学特性的作用机理，且对已有试验数据进行了统计分析。指出植被根系对土体水力学特性的改变取决于植被蒸腾、根系物理作用和根系生物化学作用三者的相对贡献，同时受根系类型、土体类型及生长阶段等因素的影响。因此，植被根系对土体水力学特性的影响十分复杂，更全面广泛的研究对于揭示植被护坡机理是亟需的。最后，探讨了植被根系影响土体水力学特性的研究空白和未来趋势。

Abstract

Under the background of global warming and "carbon peaking and carbon neutrality" strategy, vegetation slope protection has become a potential means to reinforce the slope of negative carbon emission and errosion control. The development of vegetation roots can change the soil structure and hydraulic characteristics, and then affect the stability of slope. Although some experimental studies have explored the effects of vegetation on soil hydraulic characteristics under specific conditions, the general law that vegetation roots change soil hydraulic characteristics under different conditions is not clear.In this paper, the research on vegetation transpiration, root physical function and root biochemical function are collected and reviewed, the mechanism of the effect of vegetation roots on soil hydraulic characteristics is analyzed and summarized, and the available experimental data are statistically analyzed. It is pointed out that the change of hydraulic characteristics of soil by vegetation roots depends on the relative contributions of transpiration, physical and biochemical processes of roots, at the same time by the root type, soil type and growth stage and other factors. Therefore, the effect of vegetation roots on soil hydraulic characteristics is very complex, and more comprehensive and extensive researches are needed to reveal the mechanism of vegetation slope protection. Finally, the blank and future research trend of the effect of vegetation roots on soil hydraulic characteristics are discussed.
