摘要
建立并分析了食饵具有疾病的生态-流行病(SI)模型,得到了平衡点局部稳定的充分条件,进一步分析了平衡点的全局稳定性,得到了边界平衡点和正平衡点全局稳定的充分条件。
The eco--epidemiological model (SI) with disease in the prey is established and analyzed ,and the sufficient condition in the equilibrium is obtained for local stability. Further analysis is made of the global stability in the equilibrium ,and the sufficient conditions are obtained for global stability in marginal equilibrium and the ecntral equilibrium.
