摘要： Water eutrophication is currently one of the most severe problems affecting humans worldwide. This phenomenon is particularly serious in freshwater systems in China. Thus, there is a need for a cost-effective, sustainable solution to this problem. One approach that meets all these requirements and is also ecologically friendly is the use of floating plants in the contaminated water areas. The ideal aquatic plant for ecological remediation is the water hyacinth (Eichharnia crassipes (Mart.) Solms.) is well adapted to an aquatic environment, and produces a larger biomass. This model of the controlled planting of floating plants to reuse resources from farmland was put into effect in lake Dianchi, Yunnan province (with a total planting area of 9 km(2) in 2011), which is the most seriously polluted lakes in China. In addition, this was the first large-scale implementation of the controlled planting of water hyacinths in China for treating polluted water. The results of this experimental replanting showed that the concentration of total nitrogen (TN) and phosphorus (TP) in the water decreased quickly. Thus, we hope that such an approach could be used in other polluted water bodies throughout the world to purify polluted water in a relatively short length of time.
