| 摘 要： | 通过讨论定态解的分布和分岔点，并利用数值模拟方法详细地分析了一个大小结构的自相食种群模型的解的渐近性质；研究个体之间的自相食行为对种群整体动态的影响，发现一些由于个体大小状态的非线性增长导致的大小结构种群模型的动力学特征。

| Abstract: | The asymptotical behavior of the solution of the size-structured population model with cannibalism is discussed by analyzing the bifurcation diagram of its equilibria and by using numerical simulation. The effect of cannibalism among individuals on the population dynamics is studied, and some dynamical characteristics of the size-structured population model with cannibalism, due to the nonlinear growth of an individual, are showed. |

| Keywords: | cannibalism size-structured population equilibrium bifurcation population dynamics |
