The ordinary linear regression was used to simulate the parameters variation, so as to develop diameter dynamic model. This model can be used to predict the diameter distribution and basal area in 10 years.
本研究使用回归方法模拟负指数的参数变化,得到了直径结构的预测模型,该模型可以用来预测10年内的直径结构和断面积结构。

The basal area growth model is the most important one in the integrated stand growth model.
断面积模型是全林模型系统中最重要的模型。
The results indicated that it is unbiased to estimate basal area of stand but inefficient when estimating stems per hectare by point sampling.
结果表明：点抽样估计林分断面积是无偏的，而估计林分每公顷株数效率不高。
Meanwhile, the result showed by random effects test demonstrated that basal area models of provenances planted on the same region was of no significant difference.
随机效应检查的结果表明，同一地区不同种源的断面积模型相同。
