| Abstract: | An exploited predatory-prey system is discussed.The conclusions about nonexistence,existence and uniqueness of limit cycles are obtained by using qualitative and bifurcation methods.The significance of the conclusions are interpreted at the same time. |
| |
| Keywords: | predator-prey system equilibrium limit cycle Hopf bifurcation |
