摘要
Abstract
In order to evaluate the water quality changes of Tianshan Tianchi in recent ten years,the change characteristics of the main monitoring indicators of Tianshan Tianchi in 2013-2022 were analyzed by t-test based on the water quality monitoring data of three sites in Tianshan Tianchi,and the pollutant discharge in 2025 was predicted by grey model based on the data of recent ten years.The results showed that:the main factors affecting the water quality of Tianchi Lake were total nitrogen and total phosphorus.The concentration of total nitrogen was significantly higher in wet season than in normal season,while the concentration of total phosphorus is lower in wet season than in normal season.The concentration of permanganate index,ammonia nitrogen and chlorophyll-α,which affect the evaluation of comprehensive nutrition index,were not significantly affected by wet season or normal season.The average concentration of ammonia nitrogen reached 0.17mg/L,and the highest concentration of total phosphorus was about 0.014mg/L.The maximum concentration of total nitrogen was about 0.97mg/L.Finally,based on the comprehensive pollution control measures taken by local governments in the past ten years,the causes of water quality changes were analyzed and specific suggestions were put forward.关键词
