摘要
讨论了一类2种群捕食与被捕食数学模型,其中食饵具有2个阶段即幼年和成年,并且捕食者只对成年食饵进行捕食.给出了该系统存在非负解的充分条件.
Discussed a two- species predator - prey system, a predator-prey system with stage-structure for prey, immature and mature were studied, and predator population only predatored mature population of prey. Obtained a sufficient condition of the existence of nonnegative solution to the system.
