I具切换效应的单种群动力学行为研究摘要:本文构建了一种基于单种群的动力学模型,同时包含了瞬时与非瞬时脉冲出生两种状况
为了获得系统种群灭绝和系统维持存活的控制值而采用了离散动力系统频闪映射理论
得到结论为瞬时脉冲出生量与非瞬时脉冲出生区间决定了系统种群的持续生存能力
可以作为对生物的监管与保护的理论基础

The results show that the instantaneous pulse birth rate and the non instantaneous birth interval play an important role in the persistence of the system population,Thus, it provides reliable strategic basis for realistic biological resource management and biodiversity conservation
