| Outline of Final Research Achievements |
The larch forest in eastern Siberia is the world’s largest coniferous forest. Its persistence is considered to depend on near-surface permafrost, and thus forecast warming over the 21st century and consequent degradation of near-surface permafrost is expected to affect the larch forest in Siberia.
Here, we developed an integrated land surface model to analyze how the Siberian larch forest will react to current warming trends. This model analyzed interactions between vegetation dynamics and thermo-hydrology, and it satisfactorily reconstructs latitudinal gradients in permafrost presence, soil moisture, tree leaf area index, and biomass over the entire larch-dominated area in eastern Siberia. The model showed that, under climatic conditions predicted under gradual and rapid warming, the annual net primary production of larch increased about 2 and 3 times, respectively, by the end of the 21st century compared with that in the previous century.
