摘要: 运用微分方程稳定性理论,建立了几种共生类型下种群相互依存的数学模型,分析了各个模型中的平衡点及其稳定性条件,并在此基础上讨论了两个种群在时间足够长以后的变化趋势。

关键词: 共生, 平衡点, 稳定性, 相平面, 数学模型

Abstract: Establishes several mathematical models of symbiotic interdependent population by using the stability theory of differential equations, then analyzes equilibrium points and stability conditions of each model. Finally discusses the future trend of two populations after longtime enough.

Key words: symbiosis, equilibrium point, stability, phase plane, mathematical model
