植物功能性状对城市湿地水体富营养化的响应研究进展

Advance in Response of Plant Functional Traits to Eutrophication of Urban Wetland Water

城市湿地是构成城市复合生态系统重要的生态系统类型,在维持城市生态系统安全方面具有不可替代的作用。城市湿地面临的主要问题之一是水体富营养化,主要是由于人类活动引起的氮、磷元素的过量输入和N∶P比例失调所导致的一系列生态问题。从植物全株性状、叶片性状、茎和根性状以及繁殖性状等方面综述了湿地高等植物功能性状对湿地水体富营养化的响应,并展望了今后可能的研究方向。

As an important type of complex urban ecosystem, urban wetland has an irreplaceable role in sustaining security of urban ecosystem. One of the most important issues concerning urban wetland ecosystem healthy is water eutrophication, which is among the most serious ecological problems caused by nitrogen and phosphate enrichment due to human activities. We reviewed responses of plant functional traits to water eutrophication in urban wetlands from whole plant traits, leaf traits, stem traits, root traits and reproductive traits. We outlook some potential issues to broaden our knowledge about the functional traits of wetland plants.
