摘　　要：为了全面掌握密云水库水质变化状况以及现阶段水华防治效果,本文运用单因子指数法对2021年至2022年密云水库入库水质进行分析评价,运用营养状态指数法对库区各监测断面富营养化状况进行评价,对库区浮游藻类细胞密度趋势进行监测,针对库区水生态现状探究水华防治对策。结果表明,2022年密云水库入库水质携带较高营养盐,但与2021年相比有所好转,库区营养状况呈中营养水平,库区藻细胞密度有所下降,这与水华防治措施的逐步开展密切相关。In order to comprehensively grasp the change of water quality in Miyun Reservoir and the effect of water bloom prevention and control at this stage,this paper uses the single factor index method to analyze and evaluate the water quality of Miyun reservoir from 2021 to 2022, uses the nutritional state index method to evaluate the eutrophication status of each monitoring section in the reservoir area, monitors the trend of phytoplankton cell density in the reservoir area, and explores the Countermeasures for water bloom prevention and control according to the current situation of water ecology in the reservoir area. The results show that the water quality of Miyun Reservoir in 2022 carries high nutrients, but it has improved compared with 2021. The nutritional status of the reservoir is at a medium nutritional level, and the density of algae cells in the reservoir has decreased, which is closely related to the gradual implementation of water bloom control measures.javascript: void(0).
