摘要
利用924株冷杉、844株云杉、183株白桦、158株山杨和227株落叶松解析木的数据，建立了长白山优势树种的直径生长方程。在相同的立地条件下，利用长白山245块云冷杉林、32块杨桦次生林和260块落叶松人工林固定样地，结合优势树种的直径生长方程，分析了长白山3种主要林型林分的平均直径、树高、单位面积林木平均株数和蓄积的生长过程。另外，用未参与建模的28块云冷杉林、4块杨桦次生林和30块落叶松人工林固定复测样地对拟合的3种林型林分生长过程模型进行检验，结果显示预估的相对误差为3．26％～4．96％，估计精度为95．04％～96．74％。
The analytic trees for 924 firs （ Abies fabri） , 844 spruces （ Picea asperata） , 183 birchs （ Betula platphylla） , 158 aspens （ Populus davidiana ） and 227 larchs （ Larix olgensis ） were selected to establish the models of diameter growth for dominant tree species in the Changbai Mountain. The study was conducted in 245 spruce-fir and broad-leaved mixed forests, 32 birch-aspen mixed broad leaved secondary forests, 260 plantation forests consisting of larch. At a cer-tain site, we analyzed the stand growth process for the average diameter, tree height, number of trees per unit area and volume of three dominant forest types in Changbai Mountain based on diameter growth models of the dominant tree spe-cies. Besides, the fitting growth process models were tested by the permanent sample plots of 28 spruce-fir and broad-leaved mixed forests, 4 birch-aspen mixed broad leaved secondary forests and 30 plantation forests consisting of larch which did not participate model fitting. It was found that the relative error of estimation was 3.26%-4.96% and the esti-mated accuracy was 95.04%-96.74%.
