気候変動によって東シベリアの永久凍土地域がどのくらい炭素の吸収・排出源となるか、シミュレーションモデルを用いて予測します。温暖化により永久凍土に蓄積されている大量の有機炭素がCO2の放出源となることが懸念されているため、特に土壌炭素循環に着目して植生動態モデルの改良を行っています。

The goal of this research is to predict carbon fluxes under future climate scenarios in the permafrost regions of Eastern Siberia using a simulation model. Specifically, I am focusing on soil carbon cycle processes because a large amount of carbon accumulated in permafrost can be a significant source of carbon.
