摘　　要：研究了2个斑块环境下食饵具有阶段结构、捕食者之间具有扩散、带有Holling-2的捕食-食饵模型.基于此系统解的正性和有界性结果、利用比较原理得到了系统一致持久性所满足的初始条件.A Holling-2 predator-prey model with stage structure in two-patch environment is investigated.Based on the positivity and the boundedness of the solution for the system,the uniform persistence of the solution for the system with initial conditions is proved by the principle of comparison.
