边坡生态防护是一个系统工程,边坡生态防护的主体是植物。对于边坡生态防护用植物的选择,需综合考虑边坡坡度,边坡土壤理化性质、土壤结构和土壤厚度,当地降雨和气温,以及种植目的等。文章根据北方寒冷地区公路边坡的特点,对公路边坡生态防护用植物特别是灌木和藤本植物的选择进行了探讨,具有重要的现实指导意义。只有在植物材料的选择利用中上一个新台阶,才有可能设计出集“绿化、彩化、美化”于一体的面向21世纪的现代化高等级公路绿化景观。
Ecological protection of slope is a systematic project, and the main body of slope ecological protection is plant. For slope ecological protection plant selection, we must take into account the slope gradient, slope soil physical and chemical properties, soil structure and soil thickness, local rainfall and temperature, as well as planting purposes. Based on the characteristics of highway slopes in cold northern regions, this paper discusses the selection of plants for ecological protection, especially shrubs and vines in highway slopes, which has important practical significance. Only in the selection and utilization of plant materials to a new level, it is possible to design a set of “greening, colorization, landscaping,” in one of the 21st century, modern high-grade highway green landscape.
