Outline of Research at the Start

日本国内各地の森林生態系を対象とし、炭素フローとそれに関係する各種要因について既存データの収集および新規取得を行う。さらに、安定同位体でラベルした植物遺体を埋設し、その後の分解・隔離プロセスを追跡する。各炭素フロープロセスの速度に、気候、生態系を構成する植物の形質、土壌微生物の組成、生成された土壌有機物の化学的・物理的存在形態、土壌化の程度が与える影響をモデル化する。さらに、シミュレーションを行い、炭素貯留を最大にする森林の設計を行う。

Outline of Annual Research Achievements

2023年には収集したサンプルの元素・同位体分析を行う予定であったが、Heガスの供給不足のため一部のサンプルの元素・同位体分析を行うことができなかった。2024年に無事測定を行い、解析を終了した。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

Heの供給不足により年度をまたいでしまったが、予定した解析を終え、プロジェクト全体としては研究は順調に進んでいる。

Strategy for Future Research Activity

今後は青森県で土壌採取を行い、プロジェクトで予定していた全ての地点でサンプリングと元素・同位体分析を終える見込みである。
