The water quality of L.Wuli and L.Mei1iang of L. Taihu in China, and the possibility of water cleaning by plants floating culture system were examined. The eutriphication of lake water are strongly affected by both domestic and industrial wastewater because of the about 90% of wastewater without any treatments. Eutrophication has increased in most of the Chinese lake by high anthropogenic input of nutrients with the rapid progress human activity after the 1980s. For almost elements of water of L.Wuli were more polluted compared with those of L.Meiliang. The relation of nitrogen concentration of water was NH(3-)N > NO(3-)N> N0(2-)N in L. Wuli, and NO(3-)N > NH(3-)N > NO(2-)N in L.Meiliang, respectively. From the results of water quality analysis, the nutrient concentrations were increased, but not polluted by some heavy metals and slightly increased by surfactants, anionic surface active agents. It seemed to be able to clean the lake water by plant floating culture methods with using many kinds of plants by the data of another experiments in phytotron and in natural field.
