摘　　要：岩石边坡植被生态修复是当前普遍受到关注的问题。道县武家滩位于道县、宁远、双牌三县交界处的双牌水库上游,属于一级水源保护区。分析认为,武家滩岩石边坡植被生态修复的难点在于岩石边坡缺少植物生长所需的土壤、部分坡面陡峭、进入项目地的交通道路狭窄弯曲、附近没有取土点等,建议采用无土纤维做喷播基材、在陡坡地段加挂无纺布生态挡泥条、喷播完后用椰丝毯覆盖等措施。探讨了适合武家滩岩石边坡植被生态修复的工艺流程,指出了其技术要点应从施工准备与作业面清理、修建截水沟与排水沟、安装锚杆及挂挡泥条和铁丝网、喷播无土纤维基材和种子、覆盖无纺布和椰丝毯5个方面入手,并应搞好后期的养护管理。对类似地区岩石边坡植被生态修复有一定的理论指导意义和实践应用价值。The ecological restoration of vegetation on rock slopes is currently a widely concerned issue.Wujiatan in Dao County is located upstream of Shuangpai Reservoir at the junction of Dao County,Ningyuan County,and Shuangpai County,which is a first-class water source protection area.The analysis suggests that the difficulty of vegetation ecological restoration on the rock slopes of Wujiatan lies in the lack of soil required for plant growth,steep slopes in some areas,narrow and curved traffic roads leading to the project site,and the absence of soil sampling points nearby.It is recommended to use soilless fibers as spraying substrates,add non-woven ecological mud barriers in steep slope areas,and cover with coconut silk blankets after spraying.The process flow suitable for ecological restoration of vegetation on the rock slopes of Wujiatan was discussed,and it was pointed out that the technical points should start from five aspects:construction preparation and cleaning of the work surface,construction of interception and drainage ditches,installation of anchor rods and hanging of retaining mud strips and wire mesh,spraying of soilless fiber substrates and seeds and covering with non-woven fabric and coconut silk blankets.Good maintenance management in the later stage should be done.The paper has certain theoretical guidance and practical application value for the ecological restoration of vegetation on rock slopes in similar regions.
