摘　　要：通过对长江重庆段6个断面的水质监测,分析各断面在蓄水前、蓄水期间、蓄水后水质的变化情况,研究三峡水库175m蓄水对长江重庆段水质的影响。结果表明,175m蓄水前后,长江重庆段水质总体较好且保持稳定;但主要污染物浓度在蓄水前后有所起伏,部分断面的高锰酸盐指数浓度变化较大。The impacts of 175-meter water storage in the Three Gorges Reservoir on the water quality of the Chongqing reach of the Yangtze River was studied through analysis of water quality changes before,during,and after water storage in six sections of the Chongqing reach by monitoring the water quality in these sections.The results show that before and after the 175-meter water storage,the water quality of the Chongqing reach was good in general and remained stable,the main pollutants in the water varied in concentration,and the permanganate index changed significantly in some sections.
