摘　　要：木材纤维长度是衡量木材材质、材性和植物纤维原料质量优劣的较重要的指标之一。为初步掌握人工林胡桃楸木材材质材性的径向变异规律,以其木纤维长度为研究对象,采用时间序列和一元回归两种分析方法,进行数据拟合和短期预测。研究结果表明,采用时间序列模型ARIMA和一元回归方程可以对人工林胡桃楸木纤维长度进行数据拟合与4 a短期预测,ARIMA模型的拟合效果优于一元回归方程,一元回归方程的预测效果优于ARIMA模型。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.
