摘　　要：利用2018年7月—2023年6月山美水库水质的常规理化监测日数据和附近自动气象站逐日气象观测数据,运用Pearson相关性分析方法,分析了山美水库水质监测项目和气象要素之间的相关关系,并采用综合污染指数法计算得出水质级别,再利用SPSS 16.0软件对影响水质级别的气象因子做Logistic多元回归和ROC曲线分析,得出山美水库水质与气象因子之间的关系,以及气象因子对水质诊断的最佳阈值,从而构建出气象条件与山美水库水质的关系模型,旨在为南安水库水质的管理提供气象参考。Using daily routine physical and chemical monitoring data of water quality in Shanmei Reservoir from July 2018 to June 2023 and daily meteorological observation data from nearby automatic meteorological stations,Pearson correlation analysis method was used to analyze and study the correlation between water quality monitoring projects and meteorological elements in Shanmei Reservoir.The water quality level was calculated using the comprehensive pollution index method,By using SPSS 16.0 software to perform logistic multiple regression and ROC curve analysis on meteorological factors that affect water quality levels,the relationship between water quality and meteorological factors in Shanmei Reservoir,as well as the optimal threshold for diagnosing water quality by meteorological factors,was obtained.A relationship model between meteorological conditions and water quality in Shanmei Reservoir was constructed,aiming to provide meteorological reference for the management of water quality in Nan’an Reservoir.
