三峡大坝下游河漫滩生态修复治理过程及效果

Process and Effect of Ecological Restoration of Floodplain in Downstream of Three Gorges Dam

为研究三峡大坝下游河漫滩生态修复治理,通过河漫滩形态修复、现状场地整理等物理生态修复技术,较好地阻止了河漫滩发生进一步生境退化的可能,同时结合植物种植设计和人工湿地构建等生物生态修复技术,打造河漫滩生态走廊。结果表明,所选植物有一定的耐淹性,成活率较高,较好地实现了河漫滩复绿,增加了生物多样性。

To study ecological restoration and management of floodplain in the downstream of the Three Gorges Dam, the physical ecological restoration technologies such as floodplain morphology restoration and current site consolidation were used to further prevent habitat degradation in floodplain. Combined with plant planting design and artificial wetland construction, the biological ecological restoration technologies were adopted to build floodplain ecological corridors. The results show that the selected plants have certain flooding tolerance, high survival rate, better realization of floodplain green, increased biodiversity.
