摘要
采用洋河水库2006—2021年水质监测数据,对水库水质、水体富营养状况进行评价。结果表明:河长制实施以来,入库水体主要污染指标浓度逐年降低,水质基本维持在Ⅲ类以上,水质达标率逐年上升。
The water quality and eutrophication status of the Yanghe reservoir were evaluated,based on the monitoring data of the Yanghe Reservoir from 2006—2021.The results show:Since the implementation of the river system,the concentration of the main pollution index of the reservoir water has decreased year by year,the water quality has basically remained above ClassⅢ,and the rate of water quality reaching the standard has increased year by year.
