Abstract: 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.

Key words: lakes, eutrophication, plants, ecology control, constructed wetland, ecological floating beds
