北京温榆河公园蓄水试验水生态监测成果分析及评价

Analysis and Evaluation of Water Ecological Monitoring Results of the Water Storage Experiment in Beijing Wenyuhe Park

2022年5月8日至6月6日,北京温榆河公园辛堡闸开展蓄水试验,水位由22.50m升高至25.00m。本文通过分析蓄水试验期间清河物理生境、水文、水质等水生态监测数据,采用数据收集、现场勘测、指标检测的方法,对物理生境状况、水文变化和水质状态进行了评价。结果表明,蓄水试验期间清河物理生境渠道化明显,河道水质较好,水生态系统状态良好。

From May 8,2022,to June 6,a reservoir water storage experiment was conducted at Xinpu Lock in Beijing Wenyuhe Park,during which the water level rose from 22.50 meters to 25.00 meters.This paper evaluates the physical habitat,hydrological changes,and water quality status by analyzing water ecological monitoring data collected during the reservoir water storage experiment.The assessment was carried out through data collection,on-site surveys,and indicator testing.The analysis results indicate that during the reservoir water storage experiment,the physical habitat of the Qinghe River became noticeably channelized,the river’s water quality remained good,and the water ecosystem exhibited a healthy state.
