上海淀山湖湖泊水质富营养化，对湖区生态环境造成较大威胁。根据2005~2009年淀山湖水质监测结果，应用层次分析法建立了淀山湖富营养化指标体系，对湖泊富营养化状况进行了评价。结果表明，湖泊水质总体处于中度富营养化状态。2005~2009年水质呈现好转趋势，氮、磷等营养物质含量呈现出一定程度的减少。评价方法能够体现各种因子对水质富营养化状态的影响程度，结果较为客观、可信。
上海澱山湖湖泊水質富營養化，對湖區生態環境造成較大威脅。根據2005~2009年澱山湖水質鑑測結果，應用層次分析法建立瞭澱山湖富營養化指標體繫，對湖泊富營養化狀況進行瞭評價。結果錶明，湖泊水質總體處于中度富營養化狀態。2005~2009年水質呈現好轉趨勢，氮、燐等營養物質含量呈現齣一定程度的減少。評價方法能夠體現各種因子對水質富營養化狀態的影響程度，結果較為客觀、可信。

The eutrophication of Dianshan Lake in Shanghai City threatens the ecology and environment in the lake region. On the basis of its monitoring results from 2005 to 2009, the eutrophication index system of Dianshan Lake was established by AHP method and the eutrophication situation was evaluated. The results showed that the water quality of the lake was in medium eu-trophication. However, the water quality from 2005 to 2009 was improved with the decreasing of nitrogen and phosphorus. The e-valuation method reveals the influential degree of every factor on eutrophication situation and the results are objective and relia-ble.
