Vertical Ecological Restoration Technique for the High-Steep Rock Slopes of Highway in Mountainous Area

Abstract

The ecological restoration and revegetation of high-steep rock slopes is very difficult in highway construction in the mountain area. The traditional methods of revegetation such as borrowed-soil spraying, hydro seeding are very difficult to achieve good results. This paper presents the ecosystem, composed by green geonet which can be defined as geomask net and climbing plants, its structure, construction technology and short and long term ecological effect. The ecosystem was initially applied successfully as an ecological revegetation for high-steep rock slopes in China. It was observed over four years of project that it achieved a satisfactory ecological restoration result. The technical specification for vertical ecological restoration using geomask net with climbing plants as re vegetation for high steep rock slopes of highway in mountain area was complied with the support of the Hubei Hurongxi Highway Construction head office.
