摘要:Abstract: Some biological aspects are not only affected by environmental pollution, but also have to meet the need of human being capture. Thus the biotic population problem in the environmental pollution has been taken so much attention. This paper has studied the dynamic model of a class of population living in a pol- luted environment. Based on the existing results, we have established new model with the effect of population variables on organisms and environmental toxins concentration, and with the nonlinear intrinsic growth rate and the population trapping. We have also obtained the sufficient and necessary conditions for the uniform persistence and extinction of population.
