| 中文摘要: |
| 对上海临港新城滴水湖自建成以来的水质指标进行为期6年的监测。结果表明,湖区自2004年蓄水以来,水体盐度已由3逐渐下降到2010年的1左右;N/P也呈现逐年下降的趋势,其中磷是滴水湖的营养限制元素;湖区总体水质基本维持在地表水Ⅳ～Ⅴ类,影响水质的主要污染物为CODMn、TP、TN和BOD。对湖区富营养化分析的结果表明,其富营养化程度变化趋势与水体中叶绿素a含量的变化基本一致,TP是影响其叶绿素a含量和水体富营养化程度的主要指标,且在夏秋季节容易出现富营养化指数上升的现象。 |

| Main water quality indicators of Dishui Lake in Shanghai were monitored for six consecutive years. The results showed that the salinity of the lake decreased from 3 to 1 since the impound in 2004; the N/P also showed a declining trend year by year and phosphorus was the limiting nutrient element in Dishui Lake ;the water quality in the lake remained at the level of Ⅳ to V class of surface water; the major pollutants affecting water quality were CODMn，TP，TN and BOD. The analysis of monitoring data indicated that the variation trend of eutrophication was generally consistent with that of chlorophyll a content in the lake，and TP was the main indicators impacting the chlorophyll a content and the eutrophication of the lake. In addition，eutrophication index was prone to rising in summer and autumn.
