摘　　要：作为生物多样性和生态效益最高的自然生态系统之一,湿地在城市建设过程中受到严重破坏,导致生境大量丧失,生物多样性急剧下降。为恢复练湖湿地生物多样性,改善区域生态环境质量,维持区域生态平衡,以生境修复理论为指导,针对练湖湿地不同区域的生态环境特征,采用底泥生态疏浚、生物操纵、植物浮床等多种生态修复技术,分别构建生态岛屿、森林湿地和滨岸带生境。在地形塑造的基础上,对生态系统结构和功能进行优化调整,通过搭配栽种挺水、浮水、沉水植物,适当放养底栖动物、鱼、虾等水生动物,恢复湿地植物群落、水生动物群落,最终形成结构合理的生态系统。Wetland, as one of the ecosystems with highest biodiversity and ecological benefits, was severely damaged in the process of urban construction, leading to considerable habitat loss and biodiversity decline. This study, guided by the theory of habitat restoration,aimed at recovering the biodiversity of Lianhu wetland, improving the ecological environment quality and maintaining the local ecological balance. According to the ecological environment characteristics of different regions, the study constructed ecological islands, forest wetlands and riparian habitats by using ecological restoration techniques, such as ecological dredging,biomanipulation, plant floating bed and so on. Based on terrain shaping, ecosystem structure and functions were optimized by planting emergeent, floating and submerged plants, as well as stocking aquatic animals such as zoobenthos,fishes and shrimps. The study restored plant and aquatic animal communities, which finally formed healthy ecosystems.
