研究了在2个斑块具有迁移效应和收获率的捕食者-食饵系统,其中的功能性反应函数是具有一般性的Has-sell-Varley-Holling功能性反应。利用迭合度理论连续定理,对系统的解的界的情形进行了细致分析,给出了8种可能情形,建立了多个周期解存在的充分条件。
研究瞭在2箇斑塊具有遷移效應和收穫率的捕食者-食餌繫統,其中的功能性反應函數是具有一般性的Has-sell-Varley-Holling功能性反應。利用迭閤度理論連續定理,對繫統的解的界的情形進行瞭細緻分析,給齣瞭8種可能情形,建立瞭多箇週期解存在的充分條件。

A predator prey system with dispersal and harvest , in which the functional response is the general Has-sell-Varley-Holling function is discussed .Based on continuous theorem of coincidence degree theory , the bounds of solutions of this system are analyzed , in which there are eight possible cases , the sufficient conditions of the exist-ence of multiple periodic solutions are established .
