摘要

本文以改良的Leslie-Gower捕食系统为主体,增加自然干扰的随机噪声和Gilpin-Ayala项.并研究其种群的数量的持久性、唯一性、全局稳定性以及物种灭绝的边界条件,同时通过数值模拟,验证结论和实验结果大致吻合,此研究具有生物意义.

Abstract

A modified Leslie-Gower predator-prey system as the main disturbance of the natural increase in random noise and Gilpin-Ayala terms.Persistence research and the number of its population,uniqueness,global stability and boundary conditions extinction,while numerical simulation,verification and experimental results are generally consistent with the conclusion,and this research has biological significance.
