摘要/Abstract

摘要： 根据吉林省松江河林业局所实测的落叶松人工林(Larix olgensis)临时标准地66块、固定标准地18块以及8块团状枝解析样地资料,通过对林分中优势木生长及树冠结构与动态的分析,提出适于树木生长的Korf方程并用来构造林木的潜在生长函数。选择林分密度指数(SDI)作为反映林分中林木之间平均拥挤指标。在单木竞争指标的选择上,通过引进树冠因子,并在与传统的竞争指标相比较的基础上,淡化距离因子的作用,应用优势木相对树冠表面积构造了与距离无关的单木竞争指标,以此建立了落叶松人工林单木生长模型。

关键词: 落叶松人工林, 枝解析, 树冠因子, 与距离无关的竞争指标, 单木模型

Abstract: Using 66 temporary plots, 18 permanent plots, and 8 branch analysis plots of Larix olgensis plantations, growth of dominant trees and the crown structure and dynamics of trees were analyzed. The Korf equation, which is suitable for tree growth, was used to develop potential growth function of trees. Stand density index (SDI) was applied as a quantitative index to measure mean crowd degree between trees. On selecting individual tree competition indices, tree crown variables were introduced and it was compared with conventional competition indices in order to downplay distance factor. Using relative crown surface area as the distance-independent competition indices, individual tree growth modei of Larix olgensis was developed.

Key words: Larix olgensis plantation, branch analysis, crown variables, distance-independent competition indices, individual growth mode
