通过对湖南省洞新高速公路边坡实施以生态恢复为主,工程防护为辅的植被建植技术研究,筛选出适宜于本项目区域植被恢复的乔灌草物种,并提出有代表性的物种组合方案;通过对边坡路域生态恢复技术的应用情况与技术特征的比较分析,评价并筛选出适宜于本项目路域边坡植被建植的技术措施。本项目的研究在公路边坡植被建植技术理论与实践技术方面取得创新性成果,推动公路生态恢复学学科发展。 Through the researches on the vegetation construction technology of the slope of Dongxin Expressway in Hunan Province, which mainly focuses on ecological restoration and supplemented by engineering protection, the suitable species for the restoration of vegetation in the project area are screened out and the representative species Combination program; Through the comparative analysis of the application and technical characteristics of the ecological restoration technology in the slope roadside area, the technical measures suitable for the vegetation construction of the roadside slope in this project are evaluated and screened out. The research of this project has made innovative achievements in the theoretical and practical technologies of vegetation construction of highway slope and promoted the development of highway ecological restoration science.
