主要研究具有 Holling第 II功能性反应的食饵-捕食者随机模型的统计特性。利用 Euler 离散化方法和极大似然估计方法，对具有 Holling第 II功能性反应的食饵-捕食者随机模型的参数进行估计并对其作数值模拟。结果显示极大似然估计值和真实值数据相当吻合。“,”In the paper,we consider the statistical feature of stochastic prey-predator model with Holling II functional reaction.Based on Euler discretization method and the Maximum likelihood esti-mation,we present the parameter estimation of stochastic prey-predator model with Holling II func-tional reaction.Numerical results show the effectiveness and advantage of our methods.
