随着陕西高速公路的迅速发展,环保问题的日益突出,边坡防护问题也被日益重视起来。边坡防护方法,从早期单一的工程防护逐渐向生态防护转变,采用生态护坡技术,可以大大降低边坡的防护成本,还可以通过不同植物品种的搭配,创造出不同的景观效果。但是在植物配置时,由于缺少相应的专业指导,随意性较大,造成前期景观好,后期枯死一片的现象十分普遍。通过对陕西省多条高速公路生态护坡中所采用的植物及其长势的调查,总结出陕西省不同地区常用的护坡植物,并提出不同地区最优护坡植物种子配置方案,对及时指导工程施工,具有重要的现实意义。
With the rapid development of Shaanxi Expressway and the increasingly prominent environmental protection problems, the slope protection problem has also been paid more and more attention. Slope protection methods, from a single early engineering protection gradually change to ecological protection, the use of ecological slope protection technology can greatly reduce the cost of slope protection, but also through the different plant varieties with the creation of different landscape effects. However, plant configuration, due to the lack of appropriate professional guidance, greater randomness, resulting in the early landscape is good, the late dead a phenomenon is very common. Through the investigation of the plants used in the ecological slope protection in a number of expressways in Shaanxi Province and their growing tendency, the slope protection plants commonly used in different areas of Shaanxi Province are summarized and the optimal plan of plant seed protection in different areas is proposed. It is of great importance to promptly guide the construction, It has important practical significance.
