半干旱区公路边坡植被重建是公路生态环境保护的难点,坡面植被越冬率是坡面生态工程成功与否的一个重要指标。本试验研究依托丹东-拉萨高速公路(内蒙古集宁-老爷庙标段)生态护坡工程,结果表明:喷附时间、坡向、坡度,坡面母质、坡位、冻水浇灌以及喷附基材配比等因素,都会影响护坡植物越冬能力,从而通过试验提出相应的养护措施,以改善高速公路的绿化景观效果。 Semi-arid area highway slope vegetation reconstruction is the difficulty of road ecological environment protection, and the overwintering rate of slope vegetation is an important index of slope ecological engineering success or not. Based on the ecological slope protection project of Dandong-Lhasa Expressway (Jining-Laoyemiao Miao Autonomous Section, Inner Mongolia), the study indicated that: spraying time, aspect, slope, parent material, slope position, Ratio and other factors, will affect the ability of over-winter slope protection plants, and thus through the experiment proposed conservation measures to improve the highway greening effect.
