摘要: 为了对长白落叶松人工林直径分布进行数学模拟,基于20块长白落叶松人工林样地从1986—2006年连续观测的数据,利用43个基础模型进行拟合与卡方检验,结果表明,Weibull模型拟合与检验效果最优。该研究可为落叶松人工林的合理经营和可持续发展提供参考。

Abstract: 20 sample plots of planted Larix olgensis forests from 1986 to 2006 were selected to simulate the diameter distributions for Larix olgensis plantations.The diameter distribution was fitted and checked through Chi-square test by 43 basical models.It was shown that the Weibull distribution simulated well for diameter distribution of planted Larix olgensis forest.The reference and theoretical guidance meaning were provided to the rational management and sustainable development of planted Larix olgensis forest.

Key words: diameter structure, Larix olgensis, Changbai Mountains
