永定河2020年春季生态补水水文监测分析研究

Analysis and research on ecological water supplement hydrologic monitoring of Yongding River in the spring of 2020

2020年4月20日,官厅水库开闸放水,水头穿越17 km河北幽州段,穿越170 km北京段到达崔指挥营市界后,继续向下游前行约60 km,最终与天津武清境内京沪高速桥下游800 m处的水面连成一片,实现了永定河京津冀水面连通,25年来永定河首次全线通水,通过对永定河生态补水开展地表水、地下水与水质监测,积累了大量宝贵的一手数据,为生态补水提供及时准确科学数据支撑。

On April 20,2020,the opening of the Guanting Reservoir has raised the curtain of the spring ecological water supplemenf for the Yongding River.After the water head crossed the 17 km Youzhou section in Hebei and the 170 km Beijing section to the city boundary,the Cuizhihuiying station,it continued to travel about 60 km of downstream.Finally,the water surface was connected at 800 meters downstream of the Beijing-Shanghai Expressway Bridge in Wuqing,Tianjin,and achieved the water surface connection of Beijing,Tianjin and Hebei.Yongding River have been full of water for the first time in 25 years.By monitoring the surface water,groundwater and water quality of Yongding River,a large number of valuable primary data have been accumulated to provide timely and accurate scientific data support for ecological water supplement.
