摘要
讨论了一类食饵种群被开发的两种群捕食系统.运用定性分析和分支方法给出了该系统极限环的不存在性、存在性和惟一性等结论,并对相应的生态学意义作了说明.
An exploited predatory-prey system is discussed. The conclusions about nonexistence, existence and uniqueness of limit cycles are obtained by using qualitative and bifurcation methods. The significance of the conclusions are interpreted at the same time.
