摘要
指出了近年来随着我国公路建设等工程活动的急剧增加,大规模的裸露边坡开始出现,对边坡土体的结构和原有植被产生了破坏,极易造成水土流失、边坡失稳、生态环境破坏等不良影响。边坡的生态防护不仅可以加固边坡土体,还能起到美化生态环境的作用。对边坡生态防护的主要方法进行了总结,并从水文效应和力学效应2个方面阐述了其防护机理。在此基础上,探讨了生态护坡技术目前研究中存在问题及发展的趋势。以供参考。
In recent years,with the dramatic increase of highway construction and other engineering activities in China,large-scale bare slopes begin to appear.These may cause damage to the soil structure and original vegetation of the slope,which can lead to soil erosion,slope instability,ecological environment damage and other harmful effects.Slope protection by vegetation can not only reinforce the soil of the slope,but also beautify the ecological environment.In this paper,the main methods of slope protection by vegetation are summarized,and the mechanism of slope protection by vegetation is introduced from two aspects-the hydrological effect and mechanical effect.On this basis,the existing problems and development of slope protection by vegetation are put forward.
