西北半干旱区气候干旱、土壤理化性质差、含盐量高,边坡植被快速恢复难度大。文章以青海省西宁至塔尔寺高速公路示范工程为例,通过示范工程对客土喷播、棉网状植生带、植生袋和三维土工网等4种建植技术进行了对比实验,最终筛选出适合于当地气候-土壤环境下的边坡植被快速恢复技术。 Northwest arid arid climate, poor soil physical and chemical properties, high salt content, rapid recovery of the slope vegetation is difficult. Taking the demonstration project of Xining-Ta’er Temple Expressway in Qinghai Province as an example, comparative experiments were carried out on the four kinds of planting technologies such as guest soil sowing, cotton reticular vegetative belt, planting bag and three-dimensional geo-net through the demonstration project. The final screening It is suitable for rapid recovery of slope vegetation under local climate and soil environment.
