The Effect of the Input Rate of Nutrient on a Lake Model

摘要：

In this paper,a mathematical model consisting of nutrient,phytoplankton and zooplankton has been considered,where excretion of zooplankton is considered as one of the source of nutrient.We investigate the effect of the input rate of the nutrient from outside on controlling algal bloom.From analysis,we obtain that the system has two boundary equilibria,the existence of the positive equilibrium is also discussed.Using stability analysis,we get conditions for the stability of the equilibrium.Then,we give the explanation of the effect of the input rate of nutrient on controlling water bloom.
