摘　　要：水生植物在湖泊生态修复中具有成本低、能耗小、环境扰动小和生态观赏性等特点,在湖泊治理中发挥着重要作用。分析了湖泊生态系统退化的原因及退化的形式;阐述了利用4种不同类型水生植物的化感作用、对氮磷等营养物质的吸收作用、对沉积物的吸附作用以及光合作用等对湖泊生态系统进行修复的机制和效果;介绍了国内外相关研究现状,对现有研究方法和存在的问题进行了讨论并提出了建议;对今后的研究方向进行了展望。Aquatic plants play an important role in lake restoration due to their low cost,low energy consumption,low environmental disturbance and ecological appreciation.The causes and forms of lake ecosystem degradation were analyzed.The mechanisms and effects of four different types of aquatic plants,including allelopathy,absorption of nutrients such as nitrogen and phosphorus,adsorption of sediment and photosynthesis,were expounded.The current research status at home and abroad was introduced,and the existing research methods and problems were discussed and some suggestions were put forward.The future research direction was prospected.
