摘要
研究了一类具有避难所的非自治Lotka -Volterra扩散系统 ,其中食饵种群在环境相异的两个缀块间有限制地扩散 ,并且食饵种群有逃避天敌的避难所 ,得到了系统持久性的条件 ,进一步给出了系统存在唯一全局渐近稳定周期解的充分条件 .
This paper studies a non-autonomous predator-prey diffusion model with refuges,where the prey can diffuse between two patches of heterogeneous environment,and can also choose their own refuges to avoid being preyed by their enemies. It's shown that the system can be persistent under certain conditions.Moreover,sufficient conditions are derived that guarantee the existence of a unique positive orbit which is globally asymptotically stable.
