摘要
Abstract
In order to explore the impact of heavy rainfall events on water quality and algae in Miyun Reservoir,taking heavy rainfall in Miyun Reservoir on"23·7"as an example,the upstream,reservoir and rainwater monitoring data were analyzed and compared with historical data.The results show that the rainfall enters the reservoir through the middle interlayer flow,which leads to the decrease of trans-parency,the increase of turbidity of water temperature,the decrease of conductivity and pH value.The concentration of total phosphorus increased,and the concentration of total nitrogen recovered after a short fluctuation.The density of algal cells increased and the dominant species changed.The strong ab-sorption of nitrogen by spicularia and conocystis may be one of the reasons for the decrease of total nitro-gen concentration.The paper explores in depth the changes in water quality and algal ecosystems trig-gered by heavy rainfall events in Miyun Reservoir,providing key insights for developing effective man-agement strategies to address these challenges.关键词
