喷混植生技术在高速公路岩石边坡防护和绿化中的应用

Planting on the rocky slope of freeway by spraying combined materials

随着高速公路逐渐向山区发展，在修建高速公路过程中存在大量的高填深挖的高陡边坡，环境保护越来越引起人们的高度重视。惠（州）－河（源）高速公路在“建绿色通道，走环保之路”的思想指导下，采用了喷混植草等新型边坡防护、绿化方案。在惠河高速公路进行有效的喷混植草实验基础上，总结了喷混植草技术的特点，并对喷混植草立地条件的适宜性进行了调查和分析，同时筛选了适合广东地区的喷播草种，以期推动我国高速公路建设早日走上“生态高速”的道路。

The great number of high and steep slopes which appeared in the freeway construction caused an evergrowing concern on the part of environmentalists and the public. In the construction of the Huizhou-Heyuan Freeway is adopted the grass planting on rocky slopes by spraying combined material, a new techinque of slope protection and greening. On the basis of effective tests, the characteristics of the grass planting by spraying combined material have been sunmarized. In this paper, two sample slopes treated by this way were introduced. The results showed that this new technique can successfully afforest the rock slopes in the climate of south China.
