Research Abstract |
Wet climate with largely increased in precipitation during summer and snow accumulation during winter had continued in eastern Siberia. In the present study revealed that soil moisture in the active layer had been significantly increased corresponding with thawing of permafrost near the surface, and the perennially water-logged active layer furthermore exacerbated the boreal forest habitat, namely withered and dead forests widely extended in this region. In addition, the study attempted to extract the region of degraded boreal forest in relation to permafrost degradation based on the analyses of satellite data. The method combining field survey and satellite analyses exhibited great possibility to detect permafrost and forest degradation caused by wet climate in eastern Siberia.
