摘要
三峡大坝建成后在库区两岸形成水位周期性变化的消落带,土壤侵蚀严重,原始植被消亡,导致一系列生态环境问题。三峡大坝上游偏岩子消落带生态修复项目通过采用可行的工程技术措施,选择合适的植物品种,经过1年多绿化建设及植被养护,建成具有植物多样性的消落带生态修复示范区,构建了消落带人与自然和谐相处的局部自然生态系统。本项目筛选出适宜消落带种植的植物品种,水桦、池杉、中山杉、枫杨、杂交柳、湖北海棠、疏花水柏枝、秋华柳等都表现出良好的库区水位适应性,本项目的成功实施为三峡库区消落带生态修复提供了宝贵的实践经验。
After the completion of Three Gorges Dam,a riparianzone with periodic changes of water level has been formed on both sides of the reservoir area,serious soil erosion and the disappearance of primitive vegetation have led to a series of ecological and environmental problems.Through the adoption of feasible engineering and technical measures,the ecological restoration project of Pianyanzi Riparianzone in the upstream of Three Gorges Dam has selected suitable plant species,and has built an ecological restoration demonstration area with plant diversity,and has built a local natural ecosystem in which people and nature live in harmony after more than one year of greening construction and vegetation conservation.The project screens plant varieties suitable for planting in the riparianzone,and Betula nigra,Taxodium ascendens Brongn,Taxodium hybrid zhongshanshan,Pterocarya stenoptera,hybrid willow,Malus hupehensis,Myricaria laxiflora and Salix variegata all show good adaptability to water level in the reservoir area,the successful implementation of this project has provided valuable practical experience for the ecological restoration of riparianzone in the Three Gorges Reservoir Area.
