| 摘 要： | 本文用ARIMA（2，2，0）序列模拟了林分的平均生长过程，给出了落叶松（LarixolgensisHenry）人工林林分在树高、胸径、材积三个指标上平均总生长量的2阶求和自回归滑动平均模型，经模型残量的自相关检验及预测效果检验，估测效果良好． |
| 关 键 词： | 时间序列 平稳自回归模型 林分 生长量 |

| Abstract: | By means of ARIMA (2,2,0) series, the average growth process of stand is simulated. The average second order summation auto-regressive moving model of the average total growth quantity of the artificial stand of Larix olgensis Henry is proposed on the three indexes of height,diameter at breast height and volume of trees. It is indicated that there are good results for estimation by comparing the results of self-correlation test of the residual and anticipated results. |
| Keywords: | Time series Smooth auto-regressive model Stand Growth quantity. |
