我国高速公路、高速铁路和城镇化建设的快速发展,促进了我国工程边坡生态修复技术的创新.现中国边坡生态修复技术成果,随同动车装备和筑路技术,形成了我国高速道路建设举世瞩目的三大技术进步,已成为我国"一带一路"战略重大支撑技术体系.我国"两高"建设是以牺牲土壤生态环境为代价的,产生了大量的创伤裸露边坡,生态修复及安全防护问题非常突出.本文就路域边坡土壤破坏特征、土壤生态修复本质、工程边坡林草种选择、V型槽种植带、喷混基材配置、机械化施工等几个重大技术问题的思考与技术创新途径进行了探讨,并提出了利用路域边坡土地资源发展林草种子产业的引领技术.%With the rapid development of expressway, high-speed railway and urbanization in China, the innovation research of ecological restoration technology of engineering slope in our country has been promoted. Now, the ecological restoration technology of engineering slope soil, along with the vehicle equipment and road construction technology, has formed three major technical progresses of highway construction in China and attracted worldwide attention, which has become a support system to the "One Belt, One Road" strategy of major science and technology. The "two high" road construction in our country is at the expense of soil ecological environment destruction and results in a number of damaged bare slopes. Therefore, the ecological restoration and safety protection are very prominent. This paper discussed the following major issues: 1)The essence of soil ecological restoration; 2)Characteristics of soil ecological destruction in road slope; 3)How to select trees, shrubs and grass seeds and create the biodiversity of the plant community for the engineering slope;4)V groove planting technique for high steep rock slope; 5)Substrate configuration technology for spray mixing planting; 6)Mechanized construction technology for slope vegetation construction, etc. The concept to develop the industry of trees, shrubs and grass seeds and its key technology were also put forward.
