一类受到开发或捕食的扩散种群的持续与灭绝

Persistence and extinction of diffusion populationbeing exploited or predated

利用上下解方法和Lyapunov函数理论,讨论了一类服从Logistic增长规律,且受到开发或捕食的扩散种群动态模型解的渐近性质,得到了具有重要生物学意义的结果.

Using upper and lower solution method and the theory related to Lyapunov function,the asymptotic characteristic of a diffusion population being exploited or predated is investigated.This mathematical results are of significant biologicol meaning.
