摘  要：
北运河流域闸坝工程修建,在一定程度上改变了河流的水文情势和水环境状况。以北运河重要水文站通县站1931—1990年流量资料为研究对象,对于闸坝修建前后水文情势变化进行了对比分析,同时对北运河干流关键控制性闸坝断面2004—2009年实测监测资料进行了水质评价,并对水质时空变化进行了分析。结果表明,北运河闸坝工程拦蓄导致流量减少,其中4月份流量减少最明显,非汛期较汛期下降明显;北运河水体环境质量整体上较差,基本上均为超V类水体,上游和下游水质相对优于中游水质情况,其中水质指标氨态氮、高锰酸盐指数影响较大。

摘  要：
The flow regimes and water environment of Beiyun River have been changed in certain degree with the hydraulic engineering construction.Based on the flow data of Tongxian hydrological station from1931 to 1990 year,the flow regimes before and after the hydraulic engineering construction were compared and analyzed.Moreover,water quality monitoring data from 2004 to 2009 year of Beiyun River was evaluated and the spatial and temporal changes of water quality were analyzed.The results showed that the flow reduce due to the impoundment of hydraulic engineering,the most significant decline month is April and the flow reduction is more significant during flood season than non-flood season;water environment quality of Beiyun River is poor,the class of water quality belong to super V class,upstream and downstream of water quality is relatively better than the middle,water quality index NH+4-N and CODCr are the significant impact indexes in water environment of Beiyun River.
