Abstract:
In this paper,we consider a single population model with instantaneous and non-instantaneous birth pulse in a polluted environment. By methods of ordinary differential equations and difference equations,we obtain the controlling conditions of extinct and permanence of system population. The conclusions prove management tactics for biological resource in polluted environment.
