铁路路基边坡绿化与生态防护技术

Discussion on greening and ecological slope protection technology of railway subgrade side-slope

生态防护是边坡防护的一种趋势,边坡生态防护技术在我国正处于快速发展阶段。首先简要介绍了生态防护的原理和护坡植物选择的原则,并列举了不同气候带的植物种类。然后结合国内外生态防护的发展,指出当前生态护坡技术存在的问题。最后着重分析比较了各类生态护坡技术的适用条件及其优缺点,总结出理想生态护坡技术应具备的主要功能特性,探讨了铁路生态护坡的发展方向。

As ecological slope protection technology takes the market of slope protection,China is also enjoying th benefit it extends. Under such background,the paper outlines the general principle of this newly prevaile technology. W ith an overview of the plantation in different climate zone,it suggests the preference in plantatio selection. Afterwards,it refers to the industrial development overseas,and on this basis identifies the technic challenges C hina currently faces. T he paper gives the application conditions,strengths and flaw s of differe techniques,with a performance summary of what this technology may achieve ideally. It ends with a discussion o the future of ecological slope protection technology.
