摘要:
建立一个带有Beddington-DeAngelis型功能反应与阶段结构的随机捕食-食饵模型。通过构造Lyapunov函数，证明该系统全局正解的存在唯一性，得到正解全局渐近稳定的充分条件。最后给出数值模拟来说明噪声强度对种群系统的影响。
Abstract:
In this paper,a stochastic predatorprey system with BeddingtonDeAngelis functional response and stage structure were established.It was shown that there existed a unique positive equilibrium point of the system by constructing Lyapunov functions,and sufficient conditions that the positive equilibrium point is globally asymptotically stable were obtained.Finally,numerical simulations were given to illustrate the effect of noise intensity on the population system.
