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

Abstract

Abstract: Using the theories of impulsive differential equations, we 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. The 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.

Key words: polluted environment, transient impulsive harvesting, , non-transient impulsive harvesting, interval length, extinction, permanence
