摘要
研究了一类食饵具有阶段结构和自食作用的捕食系统,证明了在一定条件下系统是持续生存的,并通过数值模拟显示结论的正确性。
A predator - prey system with stage structure and the role of cannibalism is proposed and analyzed in this paper, which is proved permanent in certain circumstances and numerical simulations are presented to illustrate the validity of the result.
