污染环境影响的流行病模型动力学行为研究

Study on the dynamic behavior of epidemic models affected by pollution environment

为了讨论空气污染物浓度和随机环境噪声对呼吸道疾病的影响,建立了一类污染环境中的流行病模型,研究了空气污染物浓度的有界性及呼吸道疾病传播的动力学性质;在此基础上,给出了系统稳定的充分条件和反馈控制向量,旨在为我国的环境流行病学研究提供一些参考和依据.

In order to study the impacts of air pollutant concentration and random environmental noise on respiratory diseases,an epidemic model in polluted environment is established,and the boundedness of air pollutant concentration and the dynamic properties of respiratory disease transmission are studied;on this basis,the sufficient conditions for the stability of the system and the feedback control vector are given,the purpose is to provide some reference basis for the study of environmental epidemiology in China.
