| Abstract: | A single population model with non-transient impulsive harvesting was conducted. By the discrete dynamical system determined by the stroboscopic map,the controlling thresholds of the permanence and extinction of this system were obtained. The results indicated that the non-transient impulsive harvesting interval plays an important role in the permanence of population,and these also provide some reliable tactic basis for the practical biological resource management. |
