| 摘 要： | 以红石林业局为研究对象,建立了长白山林区阔叶林高产大径木收获量和净收益优化模型,其中包括矩阵生长子模型,采伐成本和林木价格子模型。通过大量的省级固定样地资料,对林分生长转移概率模型和进界生长模型进行了参数估计,并对模型进行了比较和修正。林分结构优化模拟时综合考虑了林木最大保留直径(LDT),相邻径级立木株数之比(q),林分保留断面积(RBA)和择伐采伐周期4个因素。模拟结果表明,高产大径木的林分结构参数为:q=1.2、LDT=46cm、RBA≥26m2,采伐周期(C)为10–20年。表9参9。

| Abstract: | The optimum models of harvesting yield and net profits of large diameter trees for broadleaved forest were developed, of which include matrix growth sub-model, harvesting cost and wood price sub-models, based on the data from Hongshi Forestry Bureau, in Chang-bai Mountain region, Jilin Province, China. The data were measured in 232 permanent sample plots. With the data of permanent sample plots, the parameters of transition probability and ingrowth models were estimated, and some models were compared and partly modified. During the simulation of stand structure, four factors such as largest diameter residual tree (LDT), the ratio of the number of trees in a given diameter class to those in the next larger diameter class (q), residual basal area (RBA) and selective cutting cycle (C) were considered. The simulation results showed that the optimum stand structure parameters for large diameter trees are as follows: q is 1.2, LDT is 46cm, RBA is larger than 26 m2 and selective cutting cycle time (C) is between 10 and 20 years. |
