Abstract
We analyse the influence of various stochastic perturbations on prey-predator systems. The prey-predator model is described by stochastic versions of a deterministic Lotka-Volterra system. We study long-time behaviour of both trajectories and distributions of the solutions. We indicate the differences between the deterministic and stochastic models.

我们分析了各种随机扰动对捕食-食饵系统的影响。捕食-食饵模型由确定性Lotka-Volterra系统的随机版本描述。我们研究了解的轨迹和分布的长期行为。我们指出了确定性模型和随机模型之间的差异。
