Highway Slope Ecological Protection Against Erosion Mechanism And Control Effect Research

China is one of the most serious countries of soil erosion in the world, and there has a large proportion of soil erosion caused by the highway side slope. It's caused a great damage to the topography along,terrain and vegetation cover during the construction of the highway. It brings not only serious soil erosion problem but also enormous influence for the local ecological environment. Therefore, takeing a necessary protection of ecological slope in the highway's construction and future operation is an effective measure to solve the slope stability of soil erosion and maintain the ecological environment.In addition to the necessary explanations of the main factors of soil erosion on the slope, e.g.rainfall, soil, slope, soil loss, etc. the article also analyzed its erosion controlment mechanism of ecological slope vegetation.It systematically expounded the mechanical effects of its function of maintain the slope stability by vegetation's level roots and vertical roots, and studied the stems and leaves of vegetation's hydrological effects in erosion controlment at the meantime.In experimental study,the type of slope protection, selection diamond skeleton ecology slope protection, bare slope,planter the grass ecology slope protection,tree ecology slope protection, etc.were selected.Under similar rainfall condition, quantitative indicators, soil erosion quantity, vegetation degree of coverage,soil composition ingredient, etc.were used to test comprehensive comparative analysis.The result indicated that synthesis protection effect in highway side slope aspect:Diamond skeleton ecology slope protection is better than tree ecology slope protection, tree ecology slope protection is better than planter the grass ecology slope protection, planter the grass ecology slope protection is better than bare slope.
