一类具有Logistic源及饱和发生率的反应扩散模型
A reaction-diffusion model with Logistic source and saturated incidence rate
摘要
Abstract
This article establishes a SIS reaction-diffusion model with Logistic sources and saturation incidence rates.Firstly,the uniform boundedness of the model solution is proved.Secondly,the threshold dynamics of the model based on the basic reproduction number is discussed.Finally,the asymptotic behavior of the equilibrium is further analyzed when the diffusion rate approaches zero or infinity.The results indicate that the logistic growth and population mobility of susceptible population play an important role in the spread of diseases,the faster the susceptibles reach saturation,the faster the disease is eliminated.关键词
