摘要: In this paper, we propose and study the deterministic stochastic lake ecosystem models to investigate impact of terrestrial organic matter upon persistence plankton populations. By constructing Lyapunov function using LaSalle's Invariance Principle, establish global properties model. The dynamical behavior solutions fits well with some experimental results. It is concluded that plays an important role in influencing interactions between phytoplankton zooplankton. Based on fluctuations ecosystem, further develop a stochastically perturbed Theoretic analysis implies model exists stationary distribution which ergodic. key point our enhance knowledge factors governing dynamics population models.
