用光镜及扫描电镜对不同生境下的蓝桉（ＥｕｃａｌｙｐｔｕｓｇｌｏｂｕｌｕｓＬａｂｉｌｌ．）木材结构进行了解剖学观察，比较了原产地及引种到我国后不同生境下蓝桉木材结构的变化，其变化主要是木材组成分子数量特征的差异。引种到我国的蓝桉，导管分子长度，管胞的长度、直径，纤维管胞的长度及纤维长度均相对地增加；其它数量特征值减少；单孔率、射线高度变化不明显。生长在不同生境下的蓝桉扫描结构表明：引种到我国的蓝桉导管壁上的附物纹孔与原产澳洲蓝桉的导管壁上的附物纹孔有明显的区别。本研究还从野外调查和木材生态解剖的角度初步探讨了扭曲纹理的成因、走向及纹理角度的变化，结果表明：扭曲纹理均为右旋（ＲＨ）走向，其形成主要是受风、温度和年降水量等为主的多种生态因子共同作用的结果。扭曲纹理角度随海拔的升高有增大的趋势；随纬度的增加有减少的趋势。同时对影响木材结构的多种生态因子进行了综合分析。
The anatomy of the wood structure of Eucalyptus globulus Labill. Under different habitats was observed with light microscope and scanning electron microscope. The changes of wood structure of Eucalyptus globulus in different habitats were compared after origin and introduction to China. The changes were mainly wood composition Differences in molecular characterization. Introduced to our country Eucalyptus, the length of the catheter, the length of the tracheid, the diameter, the length of the tracheid cells and the fiber length are relatively increased; other quantitative eigenvalue decreases; single hole rate, the height of the radiation is not obvious. The growth of Eucalyptus in different habitats shows that the structure of Eucalyptus urophylla introduced to the wall of Eucalyptus in China is obviously different from that of Eucalyptus urophylla in the conduit wall. The study also tentatively explored the causes, trends and changes in texture angle of distorted textures from field surveys and wood ecological anatomy. The results show that the distorted textures are all RH and the formation is mainly influenced by wind, temperature and Annual precipitation and other ecological factors based on the combined effect of the results. The angle of distortion texture tends to increase with elevation, and decreases with the increase of latitude. At the same time, a comprehensive analysis of various ecological factors that affect the wood structure was carried out.
