| 摘 要： | 湿地具有去除水中营养物质或污染物质的特殊结构和功能属性,在维护流域生态平衡和水环境稳定方面发挥巨大作用。提出了流域湿地是将流域中湿地看作一个整体,研究其水质净化功能。对国内外湿地净水功能的特殊属性、湿地系统各组分对污染物质的去除作用及湿地对污染物质的去除过程研究作了不同程度的探讨。在流域的尺度上,进行了流域湿地水质净化功能的环境因子、影响流域湿地水质净化功能的重要湿地类型和流域湿地整体水质净化功能的研究,总结了流域湿地水质净化功能。对流域湿地水质净化功能未来的研究进行了讨论与展望。

| Abstract: | Wetland,located in the terrestrialaquatic transverse zone,is an important landscape and ecosystem.It is unique combination of the structural and functional attributes that sets wetlands apart from the terrestrial and aquatic ecosystems in their ability to remove or sequester the nutrients and the toxic environmental contaminants.Wetlands have strong functions in maintaining the ecological balance and the water environment stability in watersheds.The watershced wetlands is regarded as a whole to study purification functioning.Firstly,this paper makes a detail introduction to purification functioning of wetlands,including their unique attributes that contribute to removal contaminant of the treatment of the wetland components and the progress in the wetland contaminant removal.Secondly,the water quality functioning of wetlands in watersheds is the importance part of this paper.In watersheds,it consists of the local and regional-scale environmental factors that have considerable influence on wetlands functioning,the wetlands functioning categorization and wetlands as a entirety to control non-point source pollution.This paper makes a summary of the watershed wetlands purification functions in particular.Finally some problems concerned are discussed and its future study is also prospected. |
