黄土边坡生态护坡应用研究——以三原清河流域段黄土边坡治理为例

Study on Application of Ecological Protection Technology on Loess Slope——A Case Study of Loess Slope Treatment in Sanyuan Qinghe River Basin

对黄土边坡的生态保护是建立在植被的生物特性上的,利用植被的根系对边坡和路基进行固土,避免了降水和地面水流冲刷,使植被覆盖下的土壤在不同深层都能够结合成稳定不易松散的土层,避免遭受侵蚀,进而使边坡得到加固保护。黄土边坡的生态保护不仅仅只运用植物,还综合了植物及其他防护材料的特性进行边坡防护。通过研究黄土边坡的破坏机理、稳定分析;总结研究适合应用于黄土边坡生态环境的固土、耐旱、快速覆绿植物,探索既能保证生态景观效果又满足边坡稳定的生态防护措施。

The ecological protection of loess slope is based on the biological characteristics of vegetation.The root system of vegetation is used to consolidate soil on slope and subgrade,which avoids the erosion of precipitation and surface water flow.The soil covered by vegetation can be combined into a stable soil layer in different deep layers to avoid erosion,and then the slope can be reinforced and protected.Ecological protection of loess slope not only uses plants,but also integrates the characteristics of plants and other protective materials for slope protection.By studying the failure mechanism and stability analysis of loess slope,this study summarizes the soil-fixing,drought-tolerant and fast-covering plants suitable for the ecological environment of loess slope.It explores the ecological protection measures that can not only ensure the ecological landscape effect but also meet the stability of slope.
