黄土地区公路路堑边坡植物恢复新技术应用研究

The Research and Application of New Technologies for Vegetation Restoration of Cutting Slope of Highways in Loess Region

针对公路路堑边坡植被恢复难,后期养护难,养护成本高等问题和不足,以山西省大呼高速公路为研究对象,开展了植被恢复新技术——秸秆育苗钵一体化绿化技术的应用研究工作,并进行了边坡临界坡率和临界坡长、植物选择、基质配制等试验工作,研究成果可为自然条件相同或相近地区公路建设中的植被恢复提供借鉴。

This paper conducted researches on the new technologies of vegetation restoration focusing on the deficiencies and issues in vegetation restoration of cutting slope, later maintenance and high maintenance cost. The afforestation technology of straw seedlingpot integration was adopted and research works like slope critical slope ratio and critical slope length, plant selection, and substrate preparation etc. were conducted, which provided reference for the vegetation restoration in highway construction having same natural condition or in similar regions.
