摘要
应用数学生态学和微分方程定性理论,建立并讨论了一个具功能反应的微分生态系统,在给定参数满足一定的条件下,证明了该系统极限环的存在性和唯一性,以及该系统正平衡点的全局渐近稳定性。
A differential ecosystem possessing functional response is established and discussed by using the application of mathematics ecology and differential equation qualities theory. The existence and uniqueness of the system limit cycles and the global asymptotic stability of the system positive equilibrium point are proved if the given parameter satisfied certain conditions.
