Abstract

It was estimated that the Imdang-dong site of Gyungsan was constructed in the 2nd to 4th century based on excavated layers and artifacts. This study was carried out to verify the result using the dendrochronological analysis of six wooden pillars excavated at the site. As a result, it was proven that 6 specimens were not cut at the same age because their tree-ring chronologies were not synchronized each other. And more, it was reconfirmed in wiggle matching dating as confirming two of them were dated to A.D. 94-135 and A.D. 224-289, respectively. It was coincided with the above-mentioned estimated age. In wood identification, most of them were identified as Hovenia dulcis Thunb., Tilia spp., Ulmus spp. which grow usually under cool environment. Based on the result, we could conclude that the climate at that time was cooler than the present.

경산 임당 유적은 발굴된 층위와 출토된 유물을 근거로 2-4세기에 조성된 것으로 추정되었다. 본 연구는 유적지에서 출토된 목주 6점에 대해 추정된 연대를 확인하기 위하여 연륜연대분석을 실시하였다. 연륜연대분석 결과, 6점의 목주는 서로 일치하지 않아 각각 다른 시기에 벌채된 것으로 확인되었다. 6점의 목주 중 2점에 대해 위글매치법(wiggle matching)으로 방사성탄소연대를 측정한 결과에서도 각각 A.D. 94-135년과 A.D. 224-289년으로 재확인되었으며, 이는 전술의 추정연대와 일치하였다. 또한 목제유물의 수종 결과, 비교적 서늘한 환경에서 생장하는 수종(헛개나무, 피나무, 느릅나무 등)이 있음이 확인되었다. 이를 토대로 당시의 기후가 현재보다 서늘했다고 판단하였다.
