摘要
以2006-2016年10年数据,全面研究鄱阳湖总磷总氮的变化趋势,同时分析其富营养化程度,以期为鄱阳湖入湖污染物科学考察提供技术指导和理论依据。2006-2016年鄱阳湖总磷总氮浓度年均值总体呈下降趋势,总磷在Ⅲ类和Ⅳ类之间波动;2006-2016年鄱阳湖总氮浓度年均值总体呈上升趋势。
Based on the data of 2006 -2016 in 10 years ,the change trend of total nitrogen and total phosphorus of Poyang Lake comprehensive research, and analysis of eutrophication in Poyang Lake lake pollution scientific investigation and provide technical guidance and theoretical basis. The total annual average concentration of total phosphorus and total nitrogen in Poyang Lake decreased in the past 2006 -2016 years ,and the total phosphorus fluctuated between class III and class IV;the total annual average concentration of total nitrogen in Poyang Lake in the past 2006 -2016 years showed an upward trend.
