运用SWAT模型模拟厄尔尼诺和拉尼娜事件影响时段内清流河流域蓝绿水资源的时空分布规律，并利用集对分析法解析了多时间尺度下清流河流域蓝绿水资源丰枯演变特性。结果表明:厄尔尼诺和拉尼娜事件影响时段内清流河流域绿水资源分别比多年平均值高12。0 mm和69。7 mm，蓝水资源分别比多年平均值低115。7 mm和138。2mm，绿水系数分别比多年平均值高9。3％和12。9％;厄尔尼诺和拉尼娜事件影响时段内清流河流域蓝水资源均属于枯类，绿水资源属于丰类和平类;清流河流域蓝水资源在1967-1979年、1980-1992年、1993-2005年、2006-2018年4个阶段分别属于枯、平、枯、平类，绿水资源分别属于丰、平、丰、平类，蓝绿水资源丰枯演变具有一定的波动性。
Classification analysis of blue and green water based on set pair analysis in the Qingliu River Basin
Using the SWAT model to simulate the spatiotemporal distribution patterns of blue and green water resources in the Qingliu River Basin during the impact periods of El Nino and La Nina events,and using set pair analysis to analyze the evolution characteristics of blue and green water resources in the Qingliu River Basin at multiple time scales.The results showed that during the impact periods of El Nino and La Nina events,the green water resources in the Qingliu River Basin were 12.0 mm and 69.7 mm higher than the annual average,the blue water resources were 115.7 mm and 138.2 mm lower than the annual average,and the green water coefficient was 9.3％and 12.9％higher than the annual average,respectively.During the periods affected by El Nino and La Nina events,the blue water resources in the Qingliu River Basin belong to the dry category,while the green water resources belong to the wet and normal categories.The blue water resources in the Qingliu River Basin belong to the dry,normal,dry,and normal categories during the four stages of 1967-1979,1980-1992,1993-2005,and 2006-2018,respectively.The green water resources belong to the wet,normal,wet,and normal categories,indicating that the evolution of blue and green water resources in the Qingliu River Basin has certain fluctuations.
