摘要 研究了具比率依赖型功能性反应函数的两种群系统,利用微分方程定性理论得到了系统正平衡点的存在性、局部渐近稳定性及全局渐近稳定性的条件,并且由Pontryagin最大值原理得到了最优税收策略. In this paper,a two-species system with ratio-dependent and functional response is studied.The existence of positive equilibrium of the system is discussed,and under certain conditions,the positive equilibrium are local and global stable.An optimal taxation policy is obtained by Pontryagin's maximum principle.
