| 摘 要： | 对银杏（Ｇｉｎｋｇｏ ｂｉｌｏｂａ）Ｘ射线木材密度曲线分形分析，结果表明，银杏木材密度的分形维数约在１．４４３０。分形维数直观地反映了木材密度年轮内和年轮间的变化规律。与年轮宽度有一定的联系，与木材密度本身关系不大，木材密度的分形维数一般由遗传因素控制，不同树种木材分形维数是相对固定的。木质材料的分形研究，是揭示其内在规律的有效方法。

| Abstract: | The results of X-ray wood density of Ginkgo biloba showed that the wood density is fractal in inter ring. intraring and whole-disc. The fractal dimension of Ginkgo biloba wood from Jiangsu province is 1, 4430. Fractal dimension is a very important quantity of wood properties. it has relation with the ring width and has little relation with the ring density. Fractal dimension of wood density is generally controlled by genetic factors. and it is relatively fixed for different kinds of trees. The study of fractal for wooden material is an effective method for disclosing its inherent law. |
