Arima model on wood properties variation pattern of Korean larch

Abstract

In this paper, according to the theory and method of time-series analysis, the growing rings ARIMA model of wood properties variation pattern forLarix olgensis plantation was studied. The model recognition and parameter estimation were discused. The ARIMA model of wood growth ring density, growth ring widith and late wood percentage was obtained. Appling the ARIMA model which obtained from actual test fitted the variation pattern of wood growth ring forLarix olgensis. The result indicated it was an effective method that applied the ARIMA model to study wood growth ring properties variation pattern. By comparing with the actual variation pattern from test data the goodness of fit was good.
