摘要
文献[1]提出了一个带收获和自食的两种群竞争系统,讨论了该模型解的存在条件和正性,得到了一个正平衡点局部渐近稳定的充分条件,本文讨论了该平衡点的全局渐近稳定性和对成年种群的最优收获量.
The referencepresented a stagestructured competitive population model with cannibalism and harvesting of a mature population and studied the existence and positiveness of its resolution.The conditions of the existence of a locally asymptotically stable equilitium are obtained.The existence of a globally asymptotically stable equilibrium and discuss the optimal harvesting of the mature is studied.
