Outline of Final Research Achievements

To reconstruct complicated interactions between topography, permafrost, and vegetation in Siberian larch forest, the TOPMODEL, which is a physically based streamflow and water-table-depth computation scheme was implemented to a dynamic vegetation model SEIB-DGVM, which works with a thermo-hydrology model. I examined how this integrated model reasonably works, and how it can be employed for future projection of environmental conditions of the Siberian larch region.

Academic Significance and Societal Importance of the Research Achievements

東シベリアのカラマツ林帯は、日本の国土面積の10倍の面積を占める世界最大の針葉樹林帯であるが、この広大な森林帯が現在進行中の気候変動の下でいかに変化していくのかについては、世界の研究者の間でも見解が一致していない。この地域の森林変化は、全球の炭素バランスのみならず、河川流出を通じた北極海への物質流出量と海洋生産性、海氷移動を通じたオホーツク海への物質流出まで、多くの影響の方向と大きさを決める重要な要素であるため、その予測精度の向上が望まれている。
