摘要
结合病毒对旅游经济的影响及其在旅游者数量上的具体体现,将易感者和感染者作为动态系统中的被捕食种群和捕食种群,建立了具密度制约的种群竞争模型,得到了无病平衡点和地方病平衡点的渐近稳定性和疫情的控制对策.
Combining with the impact of virus on tourism economy and the number of tourists, taking susceptibles and infectives during their travels as two competitive populations in a dynamic system, the paper establishes a populating competition differential equation which seems to contain logistic terms, thus obtaining the asymptotic stability of fixed point and getting the suitable strategy to the epidemic situation.
