| 摘 要： | 在2010年全年涡湖富营养化现状调查基础上，评价了涡湖营养程度，并分析了20年来（1986年-2006年）总氮TN、总磷TP、氮磷比TN／TP和CODMn的发展趋势。结果表明，按照综合营养状态指数法，目前涡湖呈轻度富营养化，且有进一步恶化的趋势。20年来TN，TP和CODMn有较大增长，氮磷比下降。由此，提出了漏湖富营养化综合防治的建议措施，包括污染源控制、围网养殖调整、清淤工程和沉水植被恢复工程。

| Abstract: | Based on investigation of Gehu Lake during 2010, this paper evaluated the current eutrophication levels and analyzed the trend of TN, TP, TN/TP and CODM. in the past 20 years（ 1986 -2006）. The results showed that Gehu Lake is in the meso - eutrophic state according to comprehensive eutrophication state index. TN, TP and CODMn have been rising rapidly, and the ratio of N/P decreased during past 20 years. Some proposals were put forward, including pollution source control, pen fish - culture management, sediment dredging and ecological restoration. |
