摘要:
 应用帽儿山天然次生林区不同林分条件下选设的20块椴树(Tilia amurensis)固定样地的解析木调查资料,分析了多个单木竞争指标与对象木胸高断面积定期生长量的相关关系,在椴树单木胸高断面积生长模型中引入了林木自身大小、单木竞争指标和立地因子,应用回归分析法建立了帽儿山地区天然次生椴树单木胸高断面积生长模型。研究表明:天然次生林下椴树的胸高断面积定期生长量与对象木相对直径(RD)、竞争压力指数(SCI)等指标存在比较明显的相关关系。应用主分量线性组合的方法构造的综合竞争指标(MCI)包含了各竞争指标与胸高断面积生长量之间的绝大部分的相关信息,可以作为竞争指标应用于单木胸高断面积生长模型。
Abstract:
 

The data used to develop the individual tree breast height model for linden tree of secondary forests were collected from 20 linden tree permanent sample plots which were set in the secondary forest region of Maoershan area in Heilongjiang province,Northeast China. Based on the analyzed of relationship between increment of section area of breast height with many competitive indices, the model was introduced tree size, competitive status and stand status as independent variables. The results of the study shown that main competition index influence on section area increment of individual trees for secondary forests were relative diameter (RD) and then the competitive stress index (csi). The integrative index contains the most of competition information between section area of breast height increment and competitive indices and could be introduced in the model.
