蘭嶼島雅美船的拼板舟,普遍受到人類學者的關注,並紛紛發表其建造結構、船隻型式、落成儀禮、造舟樹種等相關文章。本文建基於前人研究之基礎,量取132艘現有船隻尺寸,分析部落間的差異,結果發現前山地區的椰油、漁人、紅頭,船長及槳長顯著大於後山的朗島及東清。調查期間,訪問具造舟經驗者,獲得191艘雅美船的板材資料後進行量化分析,以百分比同質性卡方考驗後,進行事後比較發現,除了船首尾龍骨各部落普遍使用欖仁舅無顯著差異之外,其他各部位的船板,部落間均有使用不同樹材的差異存在。 資料結果顯示,船板用材主要集中於6種樹種,其所佔比例估了85.45%,依使用量之多寡排序如下:欖仁舅Neonauclea reticulata、大葉山欖Palaquium formosanum、麵包樹Artocarpus incisus、綠島榕Ficus pubenervis、台東龍眼Pometia pmna旭及蘭嶼赤楠Syzygium simile。這六種樹種在雅美族人的刻意經營下,構成了蘭嶼林地的主要林分。
Many anthropologists devoted to the study of the structure, types and rites of Yami's planked boats. Basing on these literatures, we extent the research by qualitative analysis of 191 boat's structure and varify the variation of boat's size and woody material among 6 tribes of Botel Tobago Yami people mainly used six woody species to made boat. Four of them are acai (Pometia pinnata), cipoo (Artocarpus incisus), pangowen (Syzygium simil), kolitan (Palaquium formosanum) that were cut off from private forest and the other two are itap (Neonauclea reticulata), anongo (Ficus pubenervis) that cut from public forest. According to the frequency of usage, all species we sort are itap, kolitan, cipoo, anogo. acai, and pangowen.
