| Abstract: | This paper studies the existence of a kind of general Logistic population by comparison principle and differential inequality. It gives the sufficient conditions for weak persistence, extinction, β- persistence and β - extinction of the population under the conditions that the polluted environment is smaller and the cap ture is a linear function for population. |

| Keywords: | general Logistic population pollution capture persistence extinction |
