摘　　要：阐述了巢湖对生态调水的需求,并在2009年现场调水试验的基础上,分析与评价了调水对巢湖东西半湖的水质影响。调水期间,环巢湖支流汇入湖水量5.02亿m3,出湖水量6.31亿m3,湖体TP、TN分别增加77.6和619.0t,CODMn减少了517.0t。调水试验结果表明,调水结束后东半湖TP浓度增加了7.6%,TN、CODMn、Chla浓度分别减小了40.3%、8.2%、41.8%;西半湖TP、TN、CODMn、Chla浓度分别增加了82.5%、1.2%、3.9%、711.8%;西半湖浓度增加的同时,东半湖浓度在降低,调水效果明显。The Chaohu Lake＇s demand for the ecological water diversion and the impact of the water diversion on the water quality of both east- ern and western parts of Chaohu Lake based on the on-site water diversion test in 2009 were expounded. During the water diversion, the con- verged water volume of tributaries around Chaohu Lake was 502 million m3 while outflow volume was 631 million m3. The TP, TN of the lake increased for 77.6 t and 619 t separately, with CODM~ being decreased for 517 t. The test result showed that after the water diversion, the TP density of the eastern lake had been increased for 7.6% and the concentration of TN, CODM,, Chla had been increased for 40.3%, 8.2%, 41.8% separately, while that for western lake had been increased by 82.5% ,1.2% ,3.9% ,711.8% separately. When the concentration of the western lake increased, the density of eastern lake decreased simultaneously, which showed that the water diversion effect was obvious.
