摘要: 湖滨带是水陆生态交错带的一种类型,在湖泊流域生态系统中发挥着重要作用,具有较高的生态、社会和经济价值.湖滨带的功能包括:缓冲带功能、保持生物多样性及生境保护功能、护岸功能和经济美学价值.湖滨带退化的原因主要是人为因素引起的生物群落结构的逆向演替及生态功能下降,退化湖滨带生态恢复与重建的理论基础是恢复生态学,其生态恢复技术可划分为三大类:湖滨带生境恢复与重建技术、湖滨带生物恢复与重建技术、湖滨带生态系统结构与功能恢复技术.云南洱海湖滨带近3年的生态恢复与重建试验的生态调查结果表明,试验区水生植被得到恢复,水质净化作用明显,藻类得到抑制,浮游动物的构成和数量发生变化,湖滨带湿地生态系统的生物多样性和稳定性增加.

Abstract: As a kind of aquatic-terrestrial ecotone,lakeside zone plays an important role in the lake basin ecosystem,and has high ecological,social and economic values.Its functions include lake buffer,conservation of biological diversities and special habitats,dike protection from soil erosion,and economic and esthetics values.The main factors inducing lakeside zone degradation are the anthropogenic activities that caused the converse succession of communities and the decline of ecological function.The theoretical basis of ecological restoration and reconstruction of degraded lakeside zone is restoration ecology; while the technologies are of three types,i.e.,habitat restoration and reconstruction,species restoration and reconstruction,and structural and functional restoration.A three-year case study on the ecosystem restoration and reconstruction of degraded lakeside zone of Erhai Lake in Yunnan Province showed that the aquatic macrophytes were restored,purifying function was distinct,algae were restrained,and the component and individuals of zooplankton were changed.In a word,the biological diversity and stability in the degraded lakeside-zone ecosystem increased after the restoration and reconstruction.

Key words: Lakeside zone, Ecological restoration and reconstruction, Ecological function, Degraded ecosystem
