Peculiarities of forming and functioning of Siberian stone pine forests of Altai

Our long-term (more than 20 years) studies of Altai forests formed by Siberian stone pine (Pinus sibirica du Tour) allowed us to fetch out many pecularities of forming of these forests and their functioning. The representativeness of the Aktru mountain glacier basin by hydroglacioclimatologic showin...
