摘    要:文章采用洛伦茨曲线和基尼系数的统计方法,对绥化市北林区一块样地的林木胸径分布情况进行统计分析,进而确定林木分化状况和分化程度,通过实践验证了洛伦次曲线和基尼系数的统计方法可正确反映林木分化程度,可用以正确指导和确定森林经营方案.

关 键 词:洛伦茨曲线  基尼系数  胸径分布  林木分化

Abstract:Adopting statistical method by Lorenz curves & Gini coefficient,DBH distribution in a piece of plot in North Forest region in Suihua city were statistical analyzed.Situation & level of tree differentiation were determined.Lorenz curve & Gini coefficient statistical methods were proved through practice;it can accurately reflect the degree of tree differentiation & can be used to determine the proper guidance & management plan.
Keywords:Lorenz curve  Gini coefficient  DBH distribution  tree differentiation
