摘　　要：研究了污染环境下具有Beddington-DeAngelis功能性反应的二维Lotka-Volterra捕食者-食饵系统,利用比较原理给出了系统永久生存和灭绝的充分条件.This paper concentrates on the study system with Beddington-DeAngelis functional of a two-dementional Lotka-Volterra predator-prey response, located in a large capacity environment. By the obtained results, suffcient conditions which guarantee the predator and species to be permanent and extinct are given. polluted the prey
