报告摘要：A nonautonomous stoichiometric algal growth model is developed which incorporates a season-driven light intensity. We characterize the dynamics by showing positive invariance, dissipativity, boundary dynamics, and internal dynamics. Numerical simulations are presented to uncover the impacts of the seasonal light intensity and the nutrient availability on the algal dynamics. Both removing algae (RA) periodically and blocking nutrient (BN) input from rivers constantly are discussed. It is shown that the BN method is more effective to terminate algal bloom. Our model and analysis provide a possible explanation of seasonal algal bloom and give some measurements for controlling algal bloom in China’s coastal regions.
