This note studies two-species metapopulations dynamics common model considering of the affect of interspecific interaction to colonization and extinction rate and rescue effect,demostrates the conditions of two species capable of coexistence in the competitor,predator-prey or mutualist system.
在考虑种间相互作用对定居率和绝灭率的影响以及逃避效应的基础上建立了两物种相互作用的异质种群动态的一般模型 ,通过模型分析说明了竞争、捕食和互惠共生系统中两物种能够共存的条件 。
