针对群居动物在不同年龄阶段战斗能力不同的实际状况,通过设置群居动物年龄分布函数、不同年龄个体间取胜概率函数、不同年龄个体选择鹰策略的概率函数,建立了一个考虑动物年龄的鹰-鸽博弈模型,并给出了群居动物进化稳定策略的存在性,以及判断进化稳定策略的必要条件.%In view of the reality that the combat capabilities are different for social animals in different age grades,a hawk-dove game model in consideration of animal age is built by setting age distribution function of social animals, probability function of winning and selecting hawk strategy of different age individuals. The existence and the necessary condition of judging social animal's evolution stability strategy are provided.
