污染环境下具瞬时与非瞬时脉冲收获的单种群动力学模型
Dynamics of Single Population Model with Transient and Non‐transient Impulsive Harvesting in Polluted Environment
摘要
Abstract
Using the theories of impulsive differential equations , w e investigated the dynamics of a single population model with transient and non‐transient impulsive harvesting in polluted environment ,and gave the sufficient conditions for the permanence of the population .T he results show that the amount of transient impulsive harvesting and the non‐transient impulsive harvesting interval length play important roles in the permanence of the population .关键词
