摘要：

Variations in the tree line position and glacier activity in the Central and Eastern Altai regions in the Holocene were reconstructed on the basis of analysis of sixty radiocarbon and eighteen dendrochronological dates. The tree line was higher than now in the Early and Middle Holocene, and the climate was warmer and, likely, more humid. Glaciers advanced in the forests 300, 1400, and 3000-6000 years ago. In the last millennium the forest decline at the upper tree limit occurred in 1206-1256, 1445-1501, and 1642-1736.
