| 摘 要： | 根据1998年-2003年每月对太湖9个区域的水质监测数据以及水质和富营养化评价结果表明，20世纪90年代中期开始的各项太湖水环境治理工程明显地改善了TP、TN、CODMn等主要污染指标，但，IP还是超过地面水环境3类标准，TN、CODMn单项指标指示水体为中一富营养化状态。引江济太对太湖局部水域（主要是贡湖）有一定的改善作用，水质由4类水体上升至3类水体，并对富营养化状态也有一定的改善作用。研究表明，治理同时引入清水，流域水生态系统才能最终得到恢复。

| Abstract: | The result of water quality and eutrophication assessment indicated that ： （1）drawing water from Yangtze River to Taihu Lake did not improve the water quality overall; （2）water quality of part of the Taihu Lake（Gonghu Lake） improved from class Ⅳ to class Ⅲ . （3）although extensive pollution controlling projects begun from 1996 improved TP, TN, CODMn, they were higher than that of 1981, （4） research suggested that to restore water quality of Taihu Lake, pollution controlling and drawing water must be developed at the same time. |
