Ecological Protection Of The Mountain Highway Slope And Vegetation Recovery

With the quick development of highways in our country, the highway environment is been impacted seriously. The paper begins with the peculiarity of the slope in the highway of mountain area the importance of environment protecting and the imperfection of engineering protection, introduces a way whose name is Biotechnique to maintain water and soil, and to stabilize the slope.The paper states the slope Biotechnique from the characteristics of the every mode of slope Biotechnique and the technology of vegetation construction in detail. Firstly, it concludes the slope Biotechnique, analyzes its specialties and applied situation, put forwards a method that choosing the slope Biotechnique mode from texture gradient the slope corrade expense and so on; Secondly, it investigates that technology of vegetation construction from the selecting seed and the helping grow, put forwards a method that selecting the seed. Thirdly, it uses the examples of the slope Biotechnique in Loess Plateau and Qinling Moutain to illuminate. Lastly the paper discusses the coordination with the slope Biotechnique according to the landscape, gives the coordination principle and the particular demand.
