富营养化水体湿地生态修复研究与应用进展

Research and Application Progress of Eutrophic Water Wetland Ecological Restoration

水体富营养化是当前国内外急需解决的环境问题。结合国内外研究与应用进展,对影响湿地生态修复效果的因素和构建中需注意的事项作了介绍,并对湿地生态修复的研究与应用趋势进行了展望。指出了植物选择、水力条件、营养物质和温度是影响湿地修复效果的主要因素;湿地植物选择、场地搭配建设、水岸维护工程和湿地系统维护是是湿地生态修复系统构建的主要方面。植物选择和水力条件是湿地生态修复中的关键因素,尤其是植物选择仍是目前和将来湿地生态修复的研究热点,与此同时,加强湿地生态系统中基质选择、组成和应用的研究,也是将来湿地生态修复研究和应用的重要方向。

Eutrophication of water bodies is an environmental problem that needs to be solved urgently at home and abroad.In this paper,combined with the research and application progress at home and abroad,the factors affecting the effect of wetland ecological restoration and the matters needing attention in construction are introduced,and the research and application trends of wetland ecological restoration are prospected.Plant selection,hydraulic conditions,nutrients and temperature are the main factors affecting wetland restoration effects;wetland plant selection,site collocation construction,waterfront maintenance engineering and wetland system maintenance are the main aspects of wetland ecological restoration system construction.Plant selection and hydraulic conditions are the key factors in wetland ecological restoration.Especially,plant selection is still the current and future research focus of wetland ecological restoration.At the same time,strengthening the research on matrix selection,composition and application in wetland ecosystems is also an important direction for future research and application of wetland ecological restoration.
