Study on the Radial Variation of Wood Fiber Length for Manchurian Walnut Plantation
摘要
Abstract
Wood fiber length is one of the key indexes in evaluating wood properties and the quality of plant fiber raw materials. In order to have a sound understanding of wood radial variation, the wood fiber length of Manchurian walnut in different growth rings was analyzed. Time series methods and single-variable regression model were used in data fitting and short-term prediction. The re- suits showed that time series model ARIMA and single-variable regression equation can be applied to data fitting and 4-year short-term prediction of wood fiber length for Manchurian walnut plantation. Model ARIMA has a better degree of fit than single-variable regression equation, while an excellent predictive effect is obtained from the single-variable regression equation.关键词
