| 摘 要： | 小班的单位面积株数、平均胸径、平均树高、平均单株材积、平均年龄、单位面积蓄积等是森林小班最基本的特征数据，是森林资源小班调查的主要因子。以复位固定样地数据为基础，建立林分生长模型系统，包括单木材积模型、株数模型和进界模型等，并将该模型系统用于浙江省林业重点县仙居县的小班数据更新，结果较好。 |
| 关 键 词： | 林分生长模型 单株材积模型 株数模型 进界模型 数据更新 |

| Abstract: | The number of trees, mean DBH, mean tree height, mean tree volume, mean age and the standing volume per unit area are the most important characteristics of a forest subcompartment and they are the main varia- bles of subcompartment inventories. A stand growth model system including the single tree volume model, the num- ber of trees model and the ingrowth model and others was established based on the variable data collected from the fixed sample plots of the forest subcompartments. This model system was applied to the data updating for the forest subcompartments in Xianju County, one of the key forestry counties in Zhejiang Province, and the result was proved to be satisfactory. |
| Keywords: | stand growth model single tree volume model number of trees model ingrowth model data update |
