Comprehensive Evaluation and Analysis of Water Environment Quality in Tianshan Tianchi Lake
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 environ-ment prevention and control work in Tianshan Tianchi.
