Growth Model System for Continuous Forest Inventory

The Growth Model System was developed for data updating and forecasting of the National Continuous Forest Inventory.It was designed based on the inherent forest growth laws and its parameters were estimated by the modern regression methods.It was composed of the age-implicit tree model,the diameter related survival rate model,the age and number of plots based ingrowth model,and the area model.It was suitable for forest resources updating and forecasting for a large regio,for example,a province,Data of remeasured plots and trees were needed for the system development.A study case of Jiangxi Province with detailed error analyses was given.
