【Abstract】 In this paper,a predator-prey system with mutual interference and functional response is studied.We local asymptotic stability and global stability of the positive equilibrium point.Hence we find that a locally stable positive equilibrium point must be a globally stable one.Using Pontryagin maximal principle and optimizing control theory,we obtain the optimal harvesting policy.The results improve and generalize some previous results.更多还原
