摘　　要：文章收集乌梁素海水质近15年研究中TN、TP、COD、NH_3-N、叶绿素a等数据,绘制点状图和趋势对比图。研究发现:氮、磷元素含量严重超标,藻类种群数量发生改变,在2004年前后,乌梁素海水体中TN、TP、叶绿素a的含量发生变化。营养盐含量、浮游生物数量增加,且黄苔暴发,水质恶化;成因为多年营养物质积累、适宜的气候、温度机制、排放量增大等。应加强对乌梁素海富营养化多元素之间联系的研究,为其恢复良性的生态环境提供科学依据和技术支撑。In this article,the data of TN,TP,COD,NH3-N and chlorophyll a in the researches of water quality of Wuliangsuhai Sea in the past 15 years was collected,and the charts of point shape and trend comparison were plotted.The study results showed that nitrogen and phosphorus levels seriously exceeded the standard limits and the number of algae population was changed.Before and after 2004,the contents of TN,TP and chlorophyll a in Wuliangsuhai seawater were varied.Nutrient content and plankton population increased,yellow forest outbroke,and water quality was deteriorated,due to many years of nutrients accumulation,appropriate climate,temperature mechanism,and increased emission.Therefore,research of the connection between eutrophication and multiple elements in Wuliangsuhai Sea should be strengthened so as to provide scientific basis and technical support for its recovery.
