Research of Wooden Materials for Revealing a Utilization of the Paleoenvironment in Ainu Culture.

这项研究的目的是澄清在阿伊努文化中，木材作为建造房屋的材料的利用。我们分析了在北海道东部北上市“Tokorogawakakou”遗址出土的木材。我们用光学显微镜辨认这些树林。结果表明，该地区林木主要由松木组成，共鉴定出18个分类群，其中阔叶树（柳、栎、黄曲树等）约占90%。我们将这一鉴定结果与比比号的数据进行了比较。北海道中部锡濑市的8号基地和Yukanboshi C15基地。我们的结论是，在阿伊努文化中，人们从周围的森林中获取木材，并选择这些木材建造房屋。最后，我们确定了其中一个是法格斯。这是首次在北海道东部地区的历史遗址中发现来自法古斯的材料。

The research’s purpose was to clarify the utilization of woods as materials to build dwellings in Ainu culture. We analyzed woods excavated at “Tokorogawakakou ”site, in Kitami city, eastern area of Hokkaido. We made the woods identify by optical microscope. It led us to the conclusion that the woods were composed of studs, and a total of 18 taxa was identified, approximately 90% of the excavated woods were broadleaf tree (Salix, Quercus, Fraxinus,etc). We compered the results of this identification with the data at Bibi no.8 site and Yukanboshi C15 site in Citose city, the central part of Hokkaido. We concluded that in Ainu culture, the people took the timbers from surrounding forest, and selected the species for building dwellings. Finally, we identified that one of the woods was Fagus. This was first time that materials coming from Fagus were discovered at the historic site in eastern area of Hokkaido.
