捕食-食饵系统的两种群同时捕获的最优化问题

Optimal problem of two species being harvested simultaneously for prey-predator systems

对连续的捕食 -食饵系统的奇点进行了定性的分析 ,从生态学意义上解释了中心奇点外围周期解的存在性 .另外 ,给出了对此系统的两个种群同时进行捕获时得到的最大持续收益的条件 .

This paper analysizes qualitative property of the equilibrium for a continuous prey-predator systems, and illustrate the existence of periodic solutions around certer in point of ecology . In addition, the article gives the conditions of maximum sustainable economic revenue when two species of prey-predator systems are harvested simultaneously.
