摘要
探讨了一类基于比率HollingⅢ类功能性反应函数的捕食者-食饵征税模型,得到了该系统正平衡点的存在性,局部渐近稳定性和稳定性条件,并利用Pontrjagin最大值原理得到了最优税收策略.为资源管理者制定合理的资源管理政策提供了理论依据.
A Holling Ⅲ functional response of the ratio-dependent model with taxation is discussed.The existence of positive equilibrium of the system is proved and the local and global stability is investigated.An optimal taxation policy is obtained by Pontryagin′s maximum principle.
