摘要
讨论了具有不同扩散率的两种群Ａｙａｌａ竞争系统之边界平衡点和正平衡点的稳定性，得出了相关种群动力学行为的结论·同时对有扩散和无扩散时种群的动力学行为进行了比较，说明了扩散对种群持续生存的影响·
In this paper, the stabilities of boundary equilibrium and positive equilibrium of two_species Ayala competitive systems with two different diffusions are disscused, and dynamical behaviors of species is obtained. At the same time, the dynamical behaviors between systems with diffusion and those without diffusion are compared. This shows the influence of diffusions on the persistence of species.
