摘　　要：国际木材解剖学家协会手册举例3种简易识别材种方法,分别为泡沫测试、铬天青-S测试、燃烧灰烬测试,通过实验获得56个树种对应的3种鉴别特征。结果表明:56个阔叶材中有9种呈阳性反应、15种呈弱阳性反应、32种呈阴性反应;6个材种呈阳性铬天青颜色反应。在燃烧灰烬测试中,有10种呈亮白色灰烬、14种呈黄褐色灰烬、12种呈其他颜色的灰烬、19种呈带炭的灰烬,只有1种呈成炭。3种简易的木材鉴别方法能够有效收缩树种范围,同时能够为户外或进口原木的现场检验区分近似树种提供可行性依据。The IAWA(International Association of Wood Anatomists)lists 3 method for rapid identification of hardwood species,including foaming test,chrome azurol-s test,and burning ashes test.The purpose of this study is to report the results obtained from the three test methods of 56 materials.The results showed that 9 out of 56 broad-leaf materials had foaming reaction,15 species were weakly positive,and 32 species were negative.Only 6 of the 56 species of materials showed a positive chrome-blue color reaction.In burning ashes test,there are 10 species of bright white ashes,14 species burning a tan ashes,12 species burn into other color of ash,19 species of coal ash,only 1 species is burning into charcoal.These 3 simple wood identification methods can effectively identify tree species,and provide a basis for identifying imported logs and similar tree species in the field.
