Abstract:

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.

Key words: The plantation forest, Pinus koraiensis, Wood growth ring density, The dynamic variation model, Quality prediction
