| Abstract: | In this pager,we researched dynamic behaviors of Gomportz prey-predator system in polluted environment. By using comparison theorems,we analyzed the effect of impulsive toxicant input on the sys- tem, found the model was closer to the actual situation, and obtained the sufficient conditions for the global attractability of the predator extinction periodic solution of the system. |
