摘要：该模型系统根据森林生长发展的内在规律设计,并用现代回归统计方法估计参数,由年龄隐含的单木生长模型、与直径相关的保留率模型(即采伐枯损模型)、以样地平均年龄及样地数为自变量的进界模型和面积模型组成。它适用于一个较大区域(如一个省)的森林资源更新和预测。它用复测的固定样地数据和复测的样木数据建模。文章给出了用江西省的连续清查数据进行建模和预测的误差分析结果。
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.
