内蒙古中部高速公路边坡植被恢复研究

Research on vegetation restoration on highway side slope of intermediate section of Inner Mongolia

为探讨干旱半干旱地区的植被护坡效果,为道路边坡植被恢复与重建提供理论与技术依据,依托高速公路建设工程,遵循恢复生态学原理,研究了高速公路边坡植被恢复的生态效果。结果表明:1)护坡植被覆盖度必须控制在一定范围内;2)人工建植的护坡植被群落,在经过一定时间的演替后逐渐趋向当地自然群落;3)植物种的选择一定要结合所在区域的自然环境;4)坡面植被具有明显的防治坡面水土流失的效果。

To discuss the effect of slope protecting with vegetation and afford theoretical and technical references for vegetation restoration and reconstruction on highway side slope, the ecological effects of revegetation on highway side slope was studied based on the restoration ecology principle in supported highway construction project in intermediate section of Inner Mongolia, and the result shows that： 1 ） the degree of vegetation on highway side slope must be keep to some extent; 2） succession of artificial vegetation community on highway side slope can gradually incline to natural community after a lot of years; 3） the choice and use of plant species must combine with natural environment in the region; 4） vegetation on highway side slope play a prominence role for soil and water conservation.
