污染环境中具有生育脉冲的单种群模型的最优捕获问题

The Optimal Harvesting Problem of a Single Species with Birth Pulse in a Polluted Environment

研究周期性脉冲毒素输入的污染环境中具有生育脉冲的单种群捕获模型的动力学性质,通过数值模拟给出所研究系统的动力复杂性,并进一步指出脉冲捕获的时间对最大年度持续产量的影响.

In this paper, we investigate the dynamics of a single species with birth pulse in a polluted environment concenrning periodic toxicant input. By numerical simulations, we give the dynamical complexities of such system. Finally, we show that the effects of the time of pulse harvesting on the maximum annual sustainable yield.
