摘　　要：环境污染日益严重,尤其对生态系统的危害问题已经成为生态学家关注的热点问题.尽管生物数学中捕获系统数学模型的建立和发展已经比较完善,但都没有关注环境污染对捕食者、食饵两种群的影响这一因素.本文考虑到环境污染对捕获系统的影响建立新的捕食者—食饵系统的数学模型并进行数学动力学分析.The problem of environmental pollution is becoming more and more serious, the harm to the eco- system has become the hot topic of ecologists around the world. The immediate problem also ur- gently needs to solve. Although predators - prey R - M model has relatively perfect, but it doesn＇t take into account of the environmental pollution. In fact, the influence of environmental pollution on the two species of predator-prey system is very important. The environment pollution has very big effect on population of ecology system. In order to better describe the influence from pollution of the environment on the population of ecology system, the R - M predator-prey system model was improved. The result shows that the top victims of environmental pollution is human from the research and analysis of the model.

关 键 词：捕食者—食饵系统 平衡点 极限环 稳定性 环境污染
