| 摘 要： | 以大海林林业局太平沟林场不同年龄、不同密度及不同立地条件的落叶松人工林为研究对象，采用非线性回归模型的参数估计方法拟合5个削度方程，通过计算每个削度方程的拟合统计量来确定最优削度方程模型；最后通过独立检验样本数据对5个模型进行检验，验证模型Ⅲ为最优削度方程。

| Abstract: | Different ages, different density and different site conditions for the larch plantation of Taipinggou forest farm were studied. Non-linear regression model estimation of the parameters fitting five taper equation was used and through calculating each taper equation fitting statistic to determine the optimal taper equation model. Finally, Use independent inspection sample data to choose five models of the comparison for model test. To execute the comprehensive evaluation for predicting performance of the optimal taper equation. |
