Temporal-spatial Distribution Characteristics of Nitrogen,Phosphorus and Chlorophyll a in Chaohu Lake and Their Correlation with Environmental Factors
More progress has been made in the study of nitrogen,phosphorus and chlorophyll a in the waters of Chaohu Lake,but there is still a lack of studies on their spatial and temporal fugacity characteristics in all seasons and their correlation with environmental factors.In this study,a comprehensive study of nitrogen,phosphorus and chlorophyll a and environmental factors in Chaohu Lake was conducted in January,April,July and October 2021.The results showed that the main pollutants in Chaohu Lake were total nitrogen and total phosphorus,with higher pollution in the western half of the lake than in the eastern half;ammonia nitrogen and total nitrogen contributed more to the eutrophication of Chaohu Lake waters in summer than total phosphorus and chlorophyll a.Temperature and dissolved oxygen contributed to the occurrence of water blooms in summer;and the factors influencing the dynamics of nitrogen,phosphorus and chlorophyll a were seasonally specific.
