摘　　要：调水工程是一种改善水环境的工程措施,有必要对其引水效果和调度方式进行深入研究。根据常州市沿江水利枢纽2011年5月15～19日连续5 d调水试验的实测数据,分析了引水前后污染物浓度变化和引水流量与水质综合指数的关系,阐明了调水对常州市河道水环境的改善程度和范围。从水质改善的时效上看,连续3～4 d的翻水方案为较优方案。研究结果为地方水行政主管部门优化调度方案提供了技术支撑。Water diversion project is an engineering measure to improve water environment, so it is necessary to study its effect and diversion mode. On the basis of the measured data collected in 5 days from 15th to 19th, May, 2011 in the water diversion trial implemented by the hydro -junctions along the Yangtze River in Changzhou City, the relationship among pollutants concen- tration variation before and after the water diversion and water diversion discharge and water quality index is analyzed and the effect and range of river water improvement is il[lustrated. In the view of water quality improvement duration, the water pumping scheme of 3 to 4 continuous days is superior. The result can provide technical support for the regional water administration to opti- mize the operation scheme.
