摘要
根据三峡库区蓄水前后监测的水文、水质及泥沙资料,分析水文、水质、泥沙等指标的变化情况。对蓄水前后泥沙的变化引起的水质变化进行讨论。结果表明:蓄水后由于泥沙大量淤积,库区含沙量显著减小,引起相应的浑样污染物浓度明显减小.水库运行过程中应充分重视泥沙对水环境的影响。
Based on the observed water flow,sediment and water quality data from before and after the Three Gorges Reservoir impounding,changes in various indexes,including hydrology,water quality,and sediment were analyzed.The water quality changes caused by the sediment changes before and after the impounding were discussed.The results show that the sediment concentration decreases significantly due to the deposition of a large amount of sediment,which causes the corresponding total concentration of pollutants to significantly decrease.Full attention should be paid to the environmental impact of sediment on the water quality during the reservoir operation.
