In this paper, we formulate a six dimensional drug transmission model to study the effect of family education and public health education. The dynamical behaviors of the model are discussed in terms of the basic reproduction number . By constructing Lyapunov functions, we obtain the drug-free equilibrium is globally asymptotically stable if and the drug addiction equilibrium is globally asymptotically stable if . Sensitivity analyses are performed to seek for effective control measures for drug spread. The analysis show that both the family and public health education can influence the spread of drug transmission. However, the combination of family and public health education is more effective to reduce the prevalence of drugs. Some numerical simulations are given to confirm the obtained theoretical results.
在本文中,我们构建了一个六维药物传播模型来研究家庭教育和公共健康教育的效果。根据基本再生数讨论了该模型的动力学行为。通过构造李雅普诺夫函数,我们得出:如果 ,则无药平衡是全局渐近稳定的;如果 ,则药物成瘾平衡是全局渐近稳定的。进行了敏感性分析以寻求药物传播的有效控制措施。分析表明,家庭教育和公共健康教育都能影响药物传播。然而,家庭教育和公共健康教育相结合对降低毒品流行率更有效。给出了一些数值模拟来证实所获得的理论结果。
