摘要: 对于树木分枝格局分形特征的定量描述,可以加深对树木生长过程的理解。本文采用分形几何学对兴安落叶松(Larix gmelini)的分枝格局进行研究,结果表明1)兴安落叶松分枝格局是一种分形结构,存在自相似性。2)兴安落叶松分枝格局的分形维数介于1.4~1.7之间,揭示了它的结构复杂性程度和占据生态空间、利用生态空间的能力。分形维数在树木光合作用及生长发育研究中是一个有用的参数。

Abstract: The branching pattern of Larix gmelini was Described in this paper using Fractal Geometry, the results showed that, 1) The branching pattern of Larix gmelini is a kind of fractal structure, satisfying selfsimilarity law. 2) The fractal dimensions of Larix gmelini branching pattern were between 1.4~1.7, disclosed the complexity of the branching structure and the ability of ecological space occupati on and utilization. Fractal dimension is a useful parameter to the study of light utilization and growing process of tree species.

Key words: Larix gmelini, Branching pattern, Scale, S elf-similarity, Fractal dimension
