摘　　要：本文对逻辑斯谛模型进行了递归分析,得到了递归公式1/N(t+s)=(α+β)×1/N(t).该公式不仅为模型辩识提供了统计检验的方法,而且可用于估计模型的二个重要参数:环境容量k和内禀增长率r.用递归分析法拟合逻辑斯谛模型具有方法合理,计算简便以及通用性强的优点.The recursion formula [N(t + s)]-1 = α +β[N(t)]-1 of logistic Models is derived from recusive analysis. It can be used as a stotisbic method of identification of shose models and estimaxins of two importand parametersi, e, carrying capacity K and intrnsic growth rate r are obtained as a result of it. It's a reasonble method of fitting of logistic models and simpol in culculations.
