摘　　要：针对三峡大坝上游近坝段偏岩子消落带现状,提出了石笼防冲墙技术、石笼板式护坡技术、生态袋护坡技术开展生态治理与复绿实践,为植物生长构筑生存空间,提供必要的土壤基质,并防止土壤受库水浸泡及浪涌掏蚀而流失。在此基础上筛选了十几种耐水淹植物,不同高程区域配置不同植物品种,经历1个水文年的长时间淹没,乔木整体成活率为54.9%,灌木成活率为35%。其中池杉、中山杉、水桦、疏花水柏枝、秋华柳耐淹性较好,成活率较高,分别为84%、74.2%、88.3%、97%、95%,能承受长时间的过顶淹没,消落带复绿效果明显。The practice of ecological governance and reforestation was carried out by taking Pianyanzi fluctuation zone as the object,proposed the stone cage anti wall technology,stone cage plate slope protection technology,ecological bag slope protection technology,which provides the necessary soil matrix for plant growth and prevents the soil from being soaked by reservoir water and erosion.On this basis,more than a dozen species of water-resistant plants were screened,and different plant species were configured in different elevation areas.After a long period of inundation in one hydrological year,the overall survival rate of trees and shrubs was 54.9%and 35%,respectively.Among them,Taxodium ascendens Brongn,Ascendens mucronatum,Betula nigra,Myricaria laxiflora,and Salix variegata had better submergence tolerance and higher survival rates,which were 84%,74.2%,88.3%,97%,and 95%.They could withstand long-term overtop submergence,and the effect of reforestation in the water-level zone was obvious.
