Time Series Analysis of Average Current Annual Increase in Diameter of Uneven-Aged Stand

摘要：

According to Bos-Jenkins principle and ARIMA model, the time series of the average diameter Current Annual Increment of Sabina przewalskii Kom UnevenAged Stand was fitted and predicted. A model was constructed and predicted for the sample tree data by Eviews software to select the form of the optimal model. The results showed that the AR(2) model was better fitting the series of the average Diameter Current Annual Increment R2=0.4861 and Bias was small. ARIMA model was used for short-term prediction of the series of diameter, which is very useful for prediction of the diameter growth.
