【摘要】 <正> There exist too many stochastic factors effecting and disturbing the densities of harmful algae which can cause HABs in the realistic marine environment. It is necessary to establish stochastic dynamical models on HABs ecosystem. In this paper, we present a nonlinear stochastic dynamical model on typical HABs algae diatom and dianoflagellate densities and analyze its characters of stability and Hopf bifurcation.更多还原
