山体边坡的生态修复是一项系统的、综合的过程。山区公路与平原地区的公路相比,对生态环境产生的影响是巨大的,公路穿越山谷河川之间,施工时产生了大量的土石方;在自然状态下,由于有植被的防护,在出现大的降雨时,一般不会造成水土流失,但在筑路过程中,机械的扰动,开山放炮,使山体产生不稳定,不仅对沿线的原生植被造成很大的破坏,还易诱发泥石流、山体滑坡等自然灾害,危及公路司乘人员和沿线居民的安全。
Ecological restoration of mountain slope is a systematic and integrated process. Compared with the highway in the plain area, the mountainous highway has a huge impact on the ecological environment. The highway crosses the valley river and produces a large amount of earthwork during the construction. In the natural state, due to the protection of the vegetation, During rainfall, water loss and soil erosion are generally not caused. However, during road construction, mechanical disturbance and blasting of mountains cause the mountain to become unstable, which not only causes great damage to the native vegetation along the route but also easily induces debris flow and landslides Natural disasters endanger the safety of highway officers and residents along the highway.
