为了定量描述木材宏、微观细胞堆砌构造冈案的特征，进一步获取更多有关木材宏、微观构造的尢法定量捕述的信息，对18种中刚东北产木材树种的宏观弦切面、微观三切面构造图片进行了微分汁盒维数分形分析。结果丧明：1）木材细胞堆砌的宏观构造纹理和微观构造图案部具有分形特征，且能够很好地表征木材宏、微观构造纹理、l嗣案的粗糙度和秩序度；2）与针叶树材相比，阔叶树材的宏观弦切面、微观三切面图案分彤维数较高，说明阔叶树材宏、微观细胞堆砌构造图案较粗糙、秩序复杂；3）针、阔叶树材微观三切面构造斟案的分彤维数变化的一般规律为：横圳面〉弦切面〉径切面；4）在部分类型细胞被替代的条件下，树脂道、管孔、木薄肇组织在不同程度上影响了树种微观构造图案的分彤维数。

英文摘要：

In the paper, we aim to provide a quantitative description of apparent characteristics of the maeroscopic and microscopic cell-piled structure patterns of wood and acquire further information relating to wood structure, which cannot he described quantitatively. Based on the fractal analysis of differential box-counting dimension on macroscopic tangential section and microscopic tri-sectiona] structure photos of 18 species of＇ wood in northeast China, results show that： 1 ） macroscopic structural texture and microscopic structural patterns of the cell-piled wood both have fractal features, and they have ve~3~ good characteristics of macroscopic and microscopic structural texture and patterns of roughness and order; 2） compared with softwood, the macroscopic tangential section and microscopic tri-sectional patterns of hardwood have higher fractal dimensions, which shows that macroscopic and microscopic cell-piled structure patterns of hardwood are more rough and its order is more complicated; 3） the general rule for the microseopic tri-sectional structure pattern of fractal dimension of softwood and hardwood trees is ： transverse section 〉 tangential section 〉 radial section; 4） when some types of cells are substituted, the existence of resin, vessels and wood parenchyma can influence the fl＇actal dimension changes of the microscopic structural patterns of wood to various degrees.
