Outline of Final Research Achievements

In the Lena river basin of eastern Siberia, the characteristics of forest evapotransriration and photosythesis are changed by forest environmants in waterlogging durings 2005-2008, and the influences of damages for waterlogging are studied in forest physiology (A), forest ecology (B), permafrostlogy (C), and river hydrology (D).
The influences of the responses for the A, B, and C processes were appeared by the charactrestics of forests, and the evapotranspiration and photosynthesis are decreased by permafrost conditions in the waterlogging. The influences for the D response was not issued at all and was not changed by forest conditions in the waterlogging period. This phenomena is considered in the place of occurrence for the river discharge.
The influences of the responses for the smaller or the bigger groupes are appeared by evapotranspiration, photosynthesis, and permafrost characteristics.
