内容介绍：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.
