摘要
宜昌市夷陵区S287省道贯穿三峡大老岭自然保护区,由于道路修建对保护区自然山体进行开挖,边坡开挖后未采取有效的保护措施,边坡岩体自重增加,降低岩土体的抗剪强度,山体遇雨雪天气易软化、崩解、垮塌等次生地质灾害,同时也破坏了保护区自然植被和自然景观地貌,对保护区坚持走生态优先、绿色发展之路产生负面影响。针对道路边坡生态修复问题,国内外学者已从地质稳定性、植被恢复、生态工程技术等方面展开研究,并结合实际案例提出了多种修复模式。本文基于三峡大老岭自然保护区的道路边坡破坏现状,通过现场调查分析破损山体地质地貌、生态植被现状,从保护生态环境和生物多样性的角度提出拟自然生态修复的模式及对策,为保护区道路建设受损边坡生态修复提供参考。
Provincial Road S287 in Yiling District,Yichang City,Hubei Province traverses the Three Gorges Dalaoling Nature Reserve.The road construction involved excavation of natural mountain bodies within the reserve,where effective support measures were not implemented post-slope excavation.This has significantly increased the unit weight of slope rock masses,reduced the shear strength of geotechnical materials,and made mountain bodies prone to secondary geological disasters such as softening,disintegration,and collapse during rain or snow weather.Additionally,it has damaged the natural vegetation and geomorphological landscape of the reserve,negatively impacting its commitment to ecological priority and green development.Regarding ecological restoration of road slopes,domestic and international scholars have conducted research from perspectives of geological stability,vegetation recovery,and ecological engineering techniques,proposing various restoration models through practical cases.Based on the current slope damage status in the Three Gorges Dalaoling Nature Reserve,this paper analyzes the geological features and ecological vegetation conditions of damaged mountain bodies through field investigations.From the perspective of ecological environment and biodiversity conservation,it proposes a near-natural ecological restoration model and corresponding strategies,aiming to provide references for ecological rehabilitation of damaged slopes in nature reserve road construction.
