摘　　要：基于帽儿山实验林场30块天然次生林标准地中2 875株样木的实测胸径和树高数据,应用20个常见的树高—胸径模型来模拟帽儿山林场天然次生林中主要树种白桦（Betula platyphylla Suk.）、椴树（Tilia L.）、色木（Acer mono maxim）、榆树（Ulmus spp）、杨树（Populus）、蒙古栎（Querusmongolica）、核桃楸（Juglans mandshurica Maxim）、水曲柳（Fraxinus mandshurica Rupr）和黄波椤（Phellodendron amurense Rupr）的树高—胸径关系,选出了每个树种树高—胸径最优模型形式,全部最优模型的相关系数达到了0.9以上,均方根误差介于1.0~1.5,残差分布均匀,模型的拟合效果较好。应用部分独立样本检验数据对各树种最优模型进行检验,模型的平均误差很小,预估精度达到了98%以上,表明这些模型可以用来描述该树种树高的变化规律,可以为该区域开展森林资源调查和次生林结构调整、林分生长与收获等方面的研究提供理论基础。Twenty height-diameter equations were evaluated for Betula platyphylla Suk,Tilia L.,Acer mono maxim,Ulmus spp, Populus,Querusmongolica,Juglans mandshurica Maxim,Fraxinus mandshurica Rupr and Phellodendron amurense Rupr of natural secondary forest at Maoershan Forestry Center. The optimal models of each species were selected. The correlation coefficients of all optimal models were more than 0. 9,the root mean square errors were between 1. 0 and1. 5,and the distribution of residuals were uniformity. Therefore,the effect of models was very good. The optimal models of each species were verified to base on the independent sample data,the average error of model was very small,and the prediction accuracy reached more than 98%,so these models can be used to describe the change rule of the tree height,and provide the theoretical basis for forest resource survey,forest structure adjustment and stand growth and yield in the region.
