In order to study the effect of nitrogen and phosphorus removal by dominant species in typical lakes of Jiangsu Province, six typical lakes in Jiangsu Province, Baima Lake, Baoying Lake, Gaoyou Lake, Changdang Lake, Gehu Lake and Shaobo Lake, are selected as the research objects. Six dominant species are selected according to the distribution of aquatic plants in this area, explores the experiments on the absorption of nitrogen and phosphorus in surface waters of class V standard waters (TN: 2 mg/L; TP: 0.2 mg/L) by dominant aquatic plants in Jiangsu Province. The results show that the six dominant species are Phragmites australis, Zizania latifolia, Myriophyllum spicatum, Hydrilla verticillata, Trapa natans, Nymphoides peltata. Purification experiments show that the removal rate of TP and TN by Phragmites australis and Zizania latifolia is higher than that of other aquatic plants, and the removal rate of ammonia nitrogen by Myriophyllum spicatum spicata is the best.
