摘要
研究了一个带收获和自食的两种群竞争系统的模型,证明了该模型解的正性和有界性,得到了一个正平衡点局部渐近稳定的充分条件.
In this paper,a stagestructured competitive population model with cannibalism and harvesting of a mature population is studied.It is proved that the solutions are positive and bounded,and the conditions of the existence of a locally asymptotically stable equilibrium is obtained.
