| 摘 要： | 本论文通过分析混交异龄林的生长特性,以一阶常微分方程为基础,通过微分方程与概率分布的联合使用,建立了混交异龄林的生长动态预估模型。通过以长白山林区的样地材料对模型求解,检验表明,以微分方程为基础的异龄林预估模型效果很好.

| Abstract: | In the first part of the paper,through analysing the dynamic characters of the uneven-aged forest stanes and combining of the differential equations with probability distribution.A predicting system for each of two species group in a mixed uneven-aged forest stands was developed.The study showed that the predicting system is very good to predict the future situation of the mixed species uneven-aged forest stands.All the data being used in the paper is from Chang Bat Mountain. |
