摘要
研究一生中有三个阶段——卵、幼年及成年的单种群生长模型,该模型收获成年种群,得到了正平衡点全局渐近稳定的充分条件,给出了收获成年种群的最优收获策略.
In this paper, we consider a Single Species Model with Three Stage Structure hatch, immature and mature with mature populaton harvesting, we obtained sufficient conditions for the extistence of globally aymptotically stable positive equilibrium, and the optimal harvesting pohcy of matyre population is considered.
