摘要
本文建立和研究了斑块环境中的捕食与被捕食系统。主要考虑了迁移以及由迁移所引起的斑块被侵占,资源被消耗或被破坏,斑块恢复的循环过程。讨论了平衡点的存在性及其稳定性,同时对系统的全局性也进行了分析。
In this paper, differential equations models for tri-trophic metapopulations are formulated and analyzed. Dispersal and the cycle of invasion-consumption （damage）-recovery are considered. A complete analysis of existence and stability of equilibria are given. And the long term behavior of the models is also analyzed.
