Long-term dynamics of temperature regime of the forest soils under the pine, larch and birch forest has been examined on the right bank of the Lena River. The obtained results have demonstrated strong diversity and high dynamics of thermal parameters of the cryosols in Central Yakutia. Drastic fluctuations of heat supply in the cryosol active layer, both in space and in time, testify to the urgency of studying of the dynamics of energy balance in boreal forest.

Key words: Frozen soils (cryosols), weather conditions, snow cover, active layer, soil temperature regime.
