两种群都有收获率的Holling-Ⅳ型系统的定性分析

Qualitative analysis of a predator-prey system with harvesting rate under Holling-Ⅳ functional response

研究了一类捕食者种群和食饵种群都有非常数收获率的Holling-Ⅳ型系统,分析该系统的平衡点性态,讨论极限环的不存在性、存在性条件.

A predator - prey system with non - constant harvesting rate under Holling - Ⅳ functional response is investigated. The system’s equilibrium points are analyzed. The conditions for the nonexistence and existence of limit cycle are discussed.
