摘要 建立并研究了一类连续释放害虫策略的SI模型,讨论了SI模型边界平衡点的存在性和局部稳定性,证明了系统在一定条件下存在唯一的全局渐进稳定的正平衡点.最后通过数值模拟进行了验证. In this paper,a SI mathematical model concerning continous pest control strategies is proposed and investigated. It is discussed that the boundary equilibrium is existential and locally stable. It is proved that the system admits a globally asymptotically stable positive equilibrium under appreliate conditions. Furthur more, the existence of a positive equilibrium is also studied by mesns of numeril simulation.
