摘　　要：利用相关指标(叶绿素a、总磷、总氮、透明度、浮游植物密度等)分析了徐州市云龙湖水体的富营养化特征,表明磷是藻类代谢的限制性营养盐。采用综合营养状态指数法评价了湖水富营养化程度,结果显示云龙湖水体呈轻度富营养化状态,结合近10 年来的评价结果分析了云龙湖水体富营养化的变化趋势。Using relevant indexes （including chlorophylla, total phosphorus, total nitrogen, diaphaneity and phytoplankton density）to analyze the characteristics of Yunlong Lake in Xuzhou City, it indicated that the phosphorus was the limited nourishment of alga metabolism. The water eutrophication level were evaluated with using comprehensive nutrition state index in this paper, the results showed that the Yunlong Lake was on light eutrophication level. The change current of eutrophication was analyzed combining the evalued result of recent decade in Yunlong Lake.
