Abstract:
Nitrogen has a strong correlation with the outbreak of water blooms in Taihu Lake,and it is an important triggering factor. Based on multi-source data,the mechanism by which nitrogen impacts cyanobacteria blooms in Taihu Lake is discussed. The results prove that nitrogen promotes the bloom outbreak through nutrient release and recycling,forming a positive feedback with the growth of cyanobacteria. At high water temperature,the competition between cyanobacteria growth and denitrification process for nitrate nitrogen weakens the denitrifying effect of denitrifying microorganisms,resulting in the continuous bloom of Taihu Lake. Correlation analysis demonstrates significant correlations between different nitrogen forms and chlorophyll a concentrations. In addition,ammonium nitrogen and total phosphorus are the main factors to explain the change of algae growth,and their driving effects are increasing. Machine learning model results futher support that nitrogen and phosphorus have become surplus states. Therefore,reducing exogenous nitrogen input and enhancing denitrification can effectively inhibit the proliferation of cyanobacteria,which is of great significance for controlling eutrophication in Taihu Lake. The correlation mechanism between nitrogen and water bloom outbreak in Taihu Lake is analyzed from multiple levels and perspectives in this paper,aiming to provide scientific basis for water ecological restoration and water environment management decisions.
