 note = {application/pdf, 日本古代の大規模構造物の方位がどのように定められたのかを検討し、磁北や周極星・北極星による真北の測定でなく、太陽を用いた真東西の測定であったことを明らかにした。藤原京と平城京を比較すると、道路の直線性はかなりよく、ほとんど差がない。反面、藤原京の直角の振り出し精度は低く、両京の間で測量技術の飛躍があったことがうかがえる。大宝令の大尺・小尺は高麗尺と唐大尺に相当し、高麗尺は南朝尺の裏目に由来する可能性が高い。, By examining how the orientation of large-scale structures in ancient Japan was determined, I found it was not the measurement of magnetic north or the true north using circumpolar stars and polaris, but the measurement of the true east-west direction using the sun. Comparing Fujiwara and Nara capital, the linearity of both roads is fairly good, and there is almost no difference. On the other hand, the accuracy of right-angled drawing at Fujiwara capital is low, which suggests that there was a leap in surveying technology between the two capitals. The large scale and the small scale specified by Taiho Codes correspond to Koguryo scale and large scale of Tang in order. Koguryo scale probably derived from the back side of the scale of Southern Dynasty in China., 2015年度～2019年度科学研究費補助金(基盤研究(B))研究成果報告書, 15H03264},
