摘要

本文對臺灣產之十五種闊葉樹環孔材進行調查研究，就其巨觀特徵的資料建立可應用於漂流木鑑定的方法模式。將這十五種闊葉樹進行導管、木質線及薄壁組織之相關數據量化，並將相同巨觀特徵用來比較其差異。結果發現，相同特徵間具有差異性，但僅憑局部特徵的差異是無法正確或完全判別清楚，唯有同時進行多方面的比較才可以區分及鑑定樹種。不同的樹種彼此間雖然有其相似性，但整體上的巨觀特徵會有區隔，因此仍可明確分類而不至於混淆。

Fifteen ring-porous hardwood species in Taiwan were investigated to build up the database from macroscopic features for identification of driftwood. Data of vessel, ray and parenchyma from fifteen species of woods were quantified. The difference among species with same macroscopic features was examined. The results show that there were difference among different species within the same feature which is not sufficient to completely differenate the wood species. Various features should be examined simultaneously to identify different species. This means that even though there are similarities among species, the difference of macroscopic features of the whole could be used to identify those fifteen ring-porous hardwood species without confusion.
