【Abstract】 The qualitative analysis about a kind of Kolmogorov model with constant stocking rate of predator is presented in this paper.The system it studied is as follow It studies the local behaviour of feasible equilibrium points,solution’s boundedness and global asymptotic stability and the existence of limit cycle.Correspondingly,the ecological meanings are interpreted.更多还原
