| 中文摘要: |
| 对2001年— 2007年淀山湖水质监测结果进行了分析和评价。 结果表明, 淀山湖的水质均未达到Ⅱ类水质标准, 主要超标项目为氨氮、TP 、TN 、石油类、I Mn 、COD 和 BOD5 。 综合营养状态指数为60.79～63.57, 均处于中度富营养状态,chla 与石油类和透明度具有很好的相关性, 与TP具有较好的负相关性 , 与 BOD 5 具有一定的负相关性, 与水温、DO 、I Mn 、COD 、氨氮、TN 的相关性不显著。chla季节变化较为明显。 |

| The monitoring data from 2001 to 2007 were analyzed to evaluate water quality in Dianshan Lake. The resultsindicated thatthe waterquality ofDianshan Lake did notachieve waterquality standards Ⅱ.Thepollutantsoverstandard valueincluded ammonia nitrogen, TP, TN, petroleum, I Mn , COD and BOD 5 . The comprehensive nutritionalstatusindexes were from 60.79 to 63.57 to show the waterquality atmedium levelof eutrophication.
