Mirai Watanabe 研究室（国立環境研究所）

AI 要約（直近 5 年の研究成果）

Mirai Watanabe研究室は、放射能汚染と生態系機能の関係を中心に、環境における物質循環のメカニズムを明らかにする研究を進めています。特に福島原発事故後の放射性セシウムの森林生態系内での動き、農作物や野生植物への蓄積経路を調査対象としています。根の分布調査、同位体分析、微生物DNA解析といった複数の手法を組み合わせることで、汚染された食用野生植物での放射性物質濃度の地域差や季節変化を解明し、実用的な回避方法の提案につなげています。併せて、湖沼や河川などの水環境における物質の溶解・沈殿挙動、気象要因（水温、日射、風速）が与える影響を定量的に評価する研究も行っています。高頻度モニタリングデータと数値シミュレーション、機械学習を活用し、温暖化が湖沼の熱構造や酸素環境、生物生息域に及ぼす変化を予測しています。さらに、土壌微生物の機能評価や窒素・リン循環の研究を通じて、放棄水田や人工林の生態系機能の多様性を調査し、これを自然再生や地域資源の有効利用につなげる取り組みも展開しています。
