Stabilizing Effectof Cannibalism on a Structured Competitive System;

具有阶段结构的竞争系统中自食的稳定性作用

This paper discusses a single species growth model with three-stage structure(egg,immature and mature),which is a cannibalism species,that is,the mature preys on the egg,obtains sufficient conditions for the existence of globally asymptotically stable positive equilibrium,and puts forward the optimal harvesting policy of egg and mature population,respectively.

讨论了一生中有3个阶段(卵、幼虫及成虫)的单种群生长模型,且该种群为自食系统,即成虫会对卵进行捕食。

By means of a continuous theorem of coincidence degree theory, we discuss a stage-structure predator-prey system, and give out a sufficient condition of existence for periodic solution when cannibalism occurs.

利用重合度理论中的延拓定理,讨论了一个具有阶段结构的竞争系统,当发生自食现象时,给出了保证周期解存在的充分条件。
