Updating the Main Subcompartment Variables Based on Stand Growth Model
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 variables of subcompartment inventories. A stand growth model system including the single tree volume model, the number 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.
