| 摘 要： | 对两个林分因子——个胸径和树高进行Granger因果关系分析的基础上，根据Granger理论，建立了基于协整系统的林分因子自适应模型．分析了模型系散和模型结构的生物学特性．由予模型具有的自适应性，模型运行中不断修正结果，所以模型检验精度均在92％以上，更有1／3的精度达到100％．

| Abstract: | An adaptive model of stands was established based on the theory of Granger and a study of the two important stand factors - bust diameter and tree height. The biological traits of the coefficient and structure of this model were analyzed. On account of its adaptability, the model continuously amends itself in predicting values under operation. The precision of predicted values reaches 92% or above and that of one third of the values even goes to 100%. |
