- Аннотация: In Eastern Siberia, “continental” salinization is caused by predominance of evaporation above precipitation as well as the annual and long-term freezing and thawing of soil, and is characterized by a prevalence of carbonate and sulphate ions (Anisimova and Kurchatova, 2000). Active layer salt content may indicate the impact of climate warming and active layer deepening (Wolfe et al., 2000). In Central Yakutia alone there are about 16000 alases with a total area of 44 million ha. Modern disturbances and recent climatic changes continue to cause active layer deepening and activation of young thermokarsts depressions by the thawing of upper ground ice on stable areas of inter-alas meadows (Fedorov and Konstantinov, 2003). The general effect of salinity is to reduce the growth rate of vegetation or prevent growth entirely, depending on the salt-sensitivity of the vegetation (Shannon et al., 1999). The aims of this study are to assess salt accumulation in the active layer of long disturbed areas relative to intact forest, and to investigate the seasonal movement of water and salts in the active layer.
