Abstract: |
In this paper, we consider a stage-structured switched single population model with impulsive input toxin and birth pulse. By methods of ordinary differential equations and difference equations, we obtain the controlling conditions of extinct and permanence. The conclusions prove management tactics for biological resource in polluted environment. |
Key words: Environmental toxin, Birth pulse,Extinct,Permanence |
