摘　　要：本文根据人工林红松木材生长轮密度变异特点 ,采用时间序列分析法 ,建立了人工林红松木材生长轮密度的动态模型 ,对木材生长轮密度进行近期预测 ,预测结果良好。此研究结果实现了木材生长轮内的材质预测 。This paper according to the variational characteristics of wood growth ring density, by the method of time sequence statistics, the seasonal variation model of wood growth ring density was established.We can achieve short\|term forecast of wood growth ring density and early\|stage forecast of the quality of wood growth ring density. The results provided a scientific basis for processing of plantation forest.
