常张高速公路岩石边坡仿原生态植被恢复技术的应用研究

The Application of the Vegetational Recovery Technology of Simulated Primitive Ecology on the Rock Side-Slope of the Superhighway from Changde to Zhangjiajie

介绍了常张高速公路岩石边坡仿原生态植被恢复技术的施工工艺、关键技术及试验情况，指出了这一新型的生态防护技术与传统的边坡防护相比较，具有投资省、见效快，且能稳定表层边坡，综合造价仅为客土喷播植草的50％-60％，能在短期内使边坡整体环境景观效果与周边协调一致，尤其适宜于对客土喷播植草难以成活的极陡边坡（坡率大于1：0．75）的生态防护，探索出了一条适合我省实际情况的且成本低、效果好的新的生态防护模式．仿原生态植被恢复技术是常张高速公路生态防护措施的典型代表，对今后我省山区高速公路生态防护建设具有一定的指导意义．

This paper introduces the constructing craft, key skills and experimental results of the vegetational recovery technology on the rock side - slope of the superhighway from Changde to Zhangjiajie. It also pointed out that compared with the traditional side - slope protection technology, this ecological one boasts the advantages of saving the investment, taking effect quickly and stablizing the surface side - slope, while costing only 50 - 60 % of that of the spraying of soil - dressed grass seeds. It can also harmonize the overall landscape effect with the neighbourhood in a very short time, especially suitable for the extremely sharp side -slope （fatio of slope 〉 1：0.75 ）on which soil -dressed grass seeds can hardly grow. It provides a new ecological protection mode which fits for the real situation of Hunan Province, with low cost and good result. This technology typically embodies the measures of ecological protection for the superhighway from Changde to Zhangjiajie, which is meaningful for guiding the ecological protection construction of the superhighways of the mountain area of Hunan Province
