Abstract
The existence of positive solutions of the steady-state system is studied for a kind of predator-prey model under the third boundary conditions.Global bifurcation for the system is discussed by means of local bifurcation theory and global bifurcation theory,and a sufficient and necessary condition of the existence of positive solutions is obtained.
