两斑块单向脉冲扩散的两种群竞争系统的持久性

摘要

In this paper, we study a periodic competitive system for two species x, y with x impulsively unilateral diffusion in two patches. By utilizing comparison theorem and analysis methods, sufficient and realistic conditions on permanence is established.%研究了两种群x,y的周期竞争系统,其中种群x在两斑块中做单向脉冲扩散.利用比较原理和分析方法得到种群的持久性.
