Discussion on usage of shrub and herbaceous plant in river slope regulation project

The river slope environment was deteriorated by the ruin of the river slope. Using biologic ways could improve the water and soil conservation capacity of the slop, especially through planting shrub and herbaceous plants. The developed roots of plants effectively enhanced the stability of the slope through anchoring and reinforcement effect. Planting could restore the ecological functions of the slope and increase their erosion resistance ability in the relatively short period of time. Shrubs and herbs were the main plants for slope protection, and plants with the developed roots and strong resistance were usually used at present. Different soil, climatic conditions and different geographical areas were suitable for different shrub and herbaceous plant to grow, so local environmental conditions must be considered when choosing suitable plants for slope protection. If not, it would be very difficult to succeed. This paper expatiated ecology effect and slope protection mechanism of plant. It also summarized staple shrub and herbaceous plants used for river slope regulation project. Lastly, it cited a number of vegetation could be used to protect slope in northern China, and expected to make suggestions for the selection of shrub and herbaceous plants in slope protection project.
