近年来,水体富营养化及水华问题日益严峻,水体的景观和生态功能受到严重影响。如何有效控制水华,治理富营养化水体是目前水环境领域的研究热点和前沿.水生植物化感作用抑藻作为一种新型安全的生物抑藻技术近年来备受关注。本文综述了国内外水生植物化感作用抑藻研究领域的主要研究成果,包括已发现的抑藻水生植物种类、已分离鉴定得到的水生植物化感物质类型、化感物质抑藻机理等。最后提出了水生植物化感作用抑藻技术的应用和发展,及有待研究的问题,希望为今后更好地利用水生植物资源进行水环境治理研究提供参考。
In recent years, water eutrophication and algal blooms have been serious problems influencing the landscape and ecological functions of water bodies. How to control algal blooms and water eutro-phication efficiently is recognized as vanguard and hot-spot issue in the field of water environment research. The inhibitory allelopathy of aquatic plants on algae as a novel and safe alternative for algal- bloom control has aroused extensive concern recently. This article reviews the major research achievements at home and abroad in the field of inhibitory allelopathy of aquatic plants on algae, including the species of aquatic plants discovered with inhibition on algae, the types of allelochemicals isolated and identified from these aquatic plants, and the inhibitory modes of action of allelochemicals on algae, etc. Finally, the technological application and research development as well as the problems yet to be studied in the field of inhibitory allelopathy of aquatic plants on algae are raised to help make better use of aquatic plant resources for water environment research and management.
