一个具有收获和生育脉冲效应的Holling-Tanner捕食者——食饵系统分析
Analysis of a Holling-Tanner Predator-Prey System With Birth Pulse and Harvesting Effect
摘要
Abstract
The permanence and harvesting policy of a Holling-Tanner predator-prey model with birth pulse and harvesting effect is investigated. First, by the stroboscopic map, we obtain an exact periodic solution of the system which has Ricker function or Beverton-Holt function. Further, by the Floquet theorem, we prove the boundary periodic solution is always unstable. And by the comparison theorem of impulsive differential equation, we obtain the condition for permanence of the system. At last, we gain the maximum harvesting effort for the system.关键词
