摘要
考虑一类具有阶段结构捕食开发模型,运用特征根分析法和迭代法得到了系统惟一正平衡点全局渐近稳定的简练条件,进一步分析了最优收获策略问题。并举例说明所得结论。
An exploited predator-prey system is considered in which individuals may belong to one of two classes: the immature and the mature. By using eigenvalue analysis and iterative algorithm, some simple conditions for global asymptotic stability of the unique positive equilibrium are obtained. What is more,the optimal harvesting problem is further analysed.An example illustrates these results.
