| Outline of Final Research Achievements |
This research project clarified spatial and temporal variations in degradation processes in permafrost region in eastern Eurasia, based on comprehensive analyses utilizing field work for vegetation-permafrost relationship, leveling on active layer and topographical change along permafrost degradation combining remote sensing technics, permafrost hydrological analyses and improved land-surface modeling. Notable results are summarized as follows. Spatial variation in active layer thickness was closely related with vegetation changes. Spatial structure of thermokarst development precisely mapped along with vegetation and active layer conditions. The permafrost degradation was also found in water-resource form geochemical composition in spring water. Based on these findings from field work, effect of snow depth, soil organic and moss layer in land surface model were sufficiently improved the performance to simulate permafrost temperature and active layer thickness in this region.
