摘　　要：创建了一个关于大丰自然保护区半散养麋鹿种群增长的Logistic模型,该模型准确地预测了麋鹿种群的增长规律.作者通过对比和分析相关数据揭示了种群密度对糜鹿种群增长的影响并给出两个导致种群增长发生改变的临界值.In this paper the author develops a Logistic model which describe the growth of Milu population with perfect veracity. The author shows the affection of the density to tile growth of Milu population by comparing and analyzing the data and gives two critical values which will lead the changes of the growth of the population.
