摘要
城市湿地不仅有着重要的生态和经济价值,同时还服务于城市居民的人文、审美需求等社会和文化的各个方面.然而随着经济全球一体化的发展,外来植物入侵对城市湿地生态环境和物种多样性已构成不可避免的威胁.城市湿地入侵植物对城市湿地生态系统中本地植物个体适合度、生理特性、种群遗传结构、种群数量、群落种间关系、本地植物多样性以及本地植物所处的生境等多方面造成严重影响.因此,应根据城市湿地本地植物遭受的影响,加强对城市湿地外来入侵植物的有效管理及对退化城市湿地生态系统的修复.
Urban wetlands are of important values in terms of urban ecology and economy,and also in social and cultural aspects.However,due to economic globalization and rapid urbanization,exotic plants seriously threaten urban wetland ecosystems and species diversity.The invasive plants have serious impacts on the native plants in urban wetlands,including individual fitness,physiological characters,population genetic structure,population size,interspecies relations,species diversity and habitats of the native plants.Therefore,it should enhance efficient management of invasive plants in urban wetlands and restore the degraded urban wetland ecosystems according to the impacts that the native plants in urban wetland ecosystems suffer.
