| 摘 要： | 小班按自然增长形式变化的数据可以用生长模型进行更新。对于马尾松用材林Ⅳ林分生长类型来说，可以采用Ｖ＝８．４６０４８４ｅ－２２．１７２４６１／Ａ、Ｄ＝３４．７３７３３０ｅ－１７．７０３９２０／Ａ、Ｈ＝１７．８９４７９０ｅ－１４．８５９８００／Ａ来推算以后几年小班的单位蓄积、平均胸径和平均树高。经检验结果表明，其变动系数均不超过１０％，说明这三个生长模型适用于小班数据更新。

| Abstract: | Applying growth models can generate subcompartment data which follow natural growth law,the models V=8. 460 484e-22.172 460/A, D= 34. 737 330e-17. 703 920/A and H=17. 894 790e-14. 859 800/A can be applied to predict the volume per unit, average diameter at breast height (DBH) and average height after several years for masson pine timber forest Ⅳ, the testing results of these models show that their coefficients of variation are all less than 10%, therefore, the three models can be used in data-generating of subcompartments. |
