摘　　要：在综合国内外植物护坡研究的基础上,对边坡稳定性作用机理进行了详细的介绍:一是从水文效应和力学效应两个方面,对根系固土护坡机理进行了详细介绍,并着重从根-土相互作用、根增强理论模型等方面论述了植物根系固土护坡的力学效应;二是在根增强的理论方面,从根的拔出和根的拔断两个方面分析了根的增强作用;三是从加筋理论和锚固理论两个方面介绍了根系对边坡稳定性的影响,并针对目前的研究现状,提出存在的问题,探讨了植物根系固土护坡研究的发展方向。Based on the comprehensive research of vegetation protection for slope at home and abroad, this paper introduced the mechanism of effect on slope stability as follows ： first, the mechanism of root system on soil stabilization and slope protection was introduced from the aspects of hydrological and mechanical effects, with the emphasis laid on the mechanical effect thereof depending on the root-soil interaction and the theoretical root reinforcement model; second, as regards the theory of root reinforcement, the reinforcement effect of root was analyzed from the aspects of pull-out and break-off of root ; third, the effect of root system on slop stability was described from the aspects of reinforcement and anchorage theories, then in relation to the status quo of the study, the issues existed were proposed, so as to discuss the development of the study on plant roots for soil stabilization and slope protection.
