摘　　要：为研究江苏省典型湖泊优势种对氮、磷的去除效果,选取江苏省6大典型湖泊白马湖、宝应湖、高邮湖、长荡湖、滆湖以及邵伯湖作为研究对象,针对该地区水生植物分布情况筛选出6种优势种,对地表Ⅴ类标准(TN:2 mg/L;TP:0.2 mg/L)水体中氮、磷的去除效果进行探究。调查结果表明:江苏省湖泊适应性较强的6种优势种分别为芦苇、茭草、穗状狐尾藻、轮叶黑藻、野菱、荇菜。净化试验表明:茭草和芦苇对TP、TN去除率较其他水生植物高,穗状狐尾藻去除氨氮效果最好。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.
