摘要
Abstract
To study the changes in water quality and quantity,as well as the nutritional characteristics of the Daning Regulating Reservoir,based on the water quality monitoring data from 2019 to 2023,the sin-gle factor method and comprehensive pollution index method were used to evaluate the water quality sta-tus of the Daning Regulating Reservoir from 2019 to 2023,and the nutritional status index method was used to analyze the nutritional status and trends of the Daning Reservoir from 2020 to 2023;Using linear regression,analyze the correlation between water quality and storage capacity,chlorophyll-a,and other water quality indicators during flood and non flood seasons.The results indicate that the water quality meets the water quality standards of surface water sources for drinking water;The nutritional status is ba-sically moderate,and the correlation between water quality indicators and storage capacity during flood season is higher than that during non flood season;The correlation between chlorophyll a and water quali-ty indicators T,CODMn,and pH is high.Chlorophyll a shows an upward trend with water temperature T and CODMn,and a downward trend with pH.The research results provide technical support for water quali-ty protection and eutrophication prevention and control of Daning Regulating reservoir.关键词
