Abstract: 樹木年輪による気候復元は、高い時間分解能と適用範囲の広域性を特徴とする。樹木年輪気候学は、これまで多くの課題を克服しながら、現在も年輪データ時系列を過去に伸ばすことや解析対象地域を広げることをあわせて、気候に敏感に応答する年輪指標の解析が進められ、成果をあげている。本報告では、樹木年輪気候学が持ち合わせる長所と短所について整理するとともに、特に環オホーツク地域の樹木年輪気候学についての課題を提示し、同地域の古気候復元の可能性について述べる。
Tree rings possess high potential to reconstruct past climate in both temporal and spatial scale compared to any other climate proxies. During the past 100 years, developments in dendroclimatology enhanced our understanding in past climate in many parts of the world. Dendroclimatology has been applied to various tree species growing in different site conditions. Ring width, density, wood anatomical features and isotopes derived from tree rings are now used as climate proxies. In this report, the current state of dendroclimatology and the strengths and weaknesses are explained. The potential of dendroclimatological research within the pan-Okhotsk region is discussed.
