摘　　要：中国湖泊水体富营养化严重,生态治理技术因不会带来污染物且对环境影响小而受到广泛关注。对当前湖泊水体富营养化生态治理技术进行总结,指出中国北方湖泊生态治理难度大,采用具有可再生性的生物炭作为基质修复富营养水体,效果较好。另外,采用复合型人工湿地和立体生态浮床技术治理富营养水体,效果显著。当前水生植物和基质材料在湖泊富营养生态修复中发挥着重要作用,但是植物生物量利用率低,特别是基质材料退役后未能得到资源化利用,因此提出在以后的研究中应注重提高湖泊水体富营养生态治理水平,实现资源化利用,降低湖泊治理成本。Eutrophication of lake water in China is serious,and ecological control has attracted widespread attention because of its no pollution and small environmental impact.Ecological control technology of the lake water rich nutrition were summarized.It is pointed out that it is difficult to control the lake ecology in northern China,and the effect of using biochar with reproducibility as substrate to repair eutrophication water body is good.In addition,the effects of complex constructed wetland and three-dimensional ecological floating bed technology on eutrophic water body are remarkable.At present,aquatic plants and substrate materials play an important role in eutrophic restoration of lakes,but the utilization rate of plant biomass is low.Especially,the matrix materials have not been used as resources after retirement.In the future,we should pay attention to improving the level of eutrophication and ecological control of lakes,realize the utilization of resources and reduce the cost of lake control.
