摘　　要：基于天山天池2013—2022年监测数据,采用灰色聚类法评价水环境质量,相关系数r分析叶绿素a与环境因子、营养盐的相关性。结果表明:总氮浓度的变化是水质变化的主要原因;叶绿素a浓度与水位呈显著正相关,与降水量呈高度正相关。结合采取的污染防治措施,分析水质变化的主要原因,并提出针对性的建议,以便更好地推进天山天池水环境防治工作。This paper is based on the monitoring data of Tianshan Tianchi Lake from 2013 to 2022,the water environmental quality was evaluated by grey clustering method,and the correlation coefficient r was used to analyze the correlation between chlorophyll a and environmental factors and nutrient salts.The results showed that the change of total nitrogen concentration was the main reason for the change of water quality.Chlorophyll a concentration was positively correlated with water level,and highly positively correlated with precipitation.Combined with the pollution prevention and control measures,the main causes of water quality changes were analyzed,and targeted suggestions were put forward in order to better promote the water environment prevention and control work in Tianshan Tianchi.
