高速公路水土保持生态恢复——以重庆绕城高速公路南段为例

Ecological Restoration with Water and Soil Conservation on Expressway——A case the south segment of circling expressway in Chongqing

高速公路作为一种现代化的道路交通基础设施,在国民经济建设中发挥着重要作用。高速公路建设过程中大规模的土地扰动,破坏地形地貌,自然植被消失,将会引起水土流失及生物多样性减少等生态问题,这些生态问题一直受到人们的广泛关注。而路域水土保持生态恢复则是解决这一问题的关键。以重庆绕城高速公路南段为例,简述了高速公路水土流失的成因,提出了高速公路水土保持生态恢复的原则,并在水土保持生态恢复分区的基础上提出了一些水保措施。

The expressway is playing an important role in national economic construction as a kind of modern traffic infrastructure. Land-scale land disturbance in the course of expressway construction, destruction of landform and physiognomy and disappearance of vegetation, which will cause ecological problems such as water and soil erosion, bio-diversity reduction and so on. People liave always pay great attention to these ecological problems. The most important thing to solve this problem is that ecological restoration with water and soil conservation in the way area. This text takes the south segment of circling expressway in Chongqing as an example, summarizes the cause of soil erosion and the principle on ecological restoration with water and soil conservation on expressway, meanwhile, some water and soil conservation measures are proposed based on the living area of ecological restoration with water and soil conservation on expressway.
