| 摘 要： | 研究了污染环境对具有阶段结构的种群模型的影响,考虑到新生个体的出生对种群体内毒素的影响,以及死亡的种群个体将毒素带回环境。主要运用比较定理,给出了种群一致持续生存,弱持续生存和绝灭的判据。 |
| 关 键 词： | 污染环境 阶段结构 持续生存 绝灭 |

| Abstract: | This paper concentrates on the study of the behavior of populations which has the period stages.Assume that a born organism takes with a quantity of internal toxicant,and the amount of toxicant stored in the died organisms giving into the environment.Sufficient criteria on uniform persistence,weak persistence and extinction of the consumer population are obtained by using comparison theorem. |
| Keywords: | polluted environment period stage persistence extinction |
