摘　　要：岱海是国家级重要湿地,同时也是内蒙古自治区级湖泊湿地自然保护区。近年来,岱海湖面萎缩、水质恶化等问题较为突出。为研究此问题,采用1974—2018年共45 a的水质监测数据进行岱海水质空间分布特征、变化规律及成因分析,并利用SPSS软件进行了岱海水质-水量的相关性分析。结果显示:岱海水质变化与外来污染物的输入量、湖区蓄水量显著相关,岱海水环境改善需要从削减污染物入湖量和生态补水两个方面着手进行。这些结论和建议可为决策者制定合理有效的水环境管理方案提供参考。Daihai Lake is an important national wetland and also an autonomous region-level lake and wetland nature reserve.In recent years,problems such as the shrinking surface of Daihai Lake and the deterioration of water quality have become increasingly prominent.To investigate the reasons,we used the 45-year water quality monitoring data from 1974 to 2018 to analyze the spatial distribution characteristics,changing laws and causes of the water quality of Daihai Lake,and used SPSS software to analyze the correlation relationship between water quality and water volume.The results show that the water quality change of Daihai Lake is significantly related to the input of external pollutants and the amount of water storage in the lake area.The improvement of the water environment of Daihai Lake should start from the two aspects of the reduction of pollutants into the lake and the water transfer.These can provide references for decision makers to make reasonable and effective water environment management plan.
