Abstract: Taking the fish pond of Huayu Garden Ecological Nursery as the research object, total nitrogen （TN）, total phosphorus （TP）, ammonia nitrogen and chemical demand （COD） in water before and after planting ecological floating bed as evaluation indexes, the water quality was tested. Respectively from two dimensions of time and space,the absorption effect of ecological floating bed on nitrogen and phosphorus in water and the influence trend of of COD in water were analyzed and compared. The results showed that the ecological floating bed for the whole water of nitrogen and phosphorus and COD has certain absorption effect, including removal rate up to 15.2% of total nitrogen, total phosphorus removal rate up to 56.3%. The management concept of ecological floating bed for fish pond water purification was put forward.

Key words: fish ponds, ecological floating bed, water purification evaluation, management
