| Popis: | The correlation between climatic changes and the numbers of trees in the generations of Siberian spruce (Picea obovata Ledeb.) in subgoltsy tree stands of the Southern Urals was analyzed over the past 200 years. The results showed that the most abundant generations appeared in 1809-1816, 1821-1827, 1839-1845, 1850-1867, 1875-1887, 1891-1896, 1900-1904,1911-1918, 1923-1932, 1944-1952, 1958-1966, and 1975-1995. Their formation proved to be related to the improvement of thermal conditions of the warm season during the five to seven years before and after the emergence of trees and conditions of the cold season in the year of their emergence, as well as to the periods of increased snow depth in late April in the years 27-32 of tree growth. This work was performed within the framework of a joint project conceived by the Ural State Forest Engineering University and Swiss Federal Research Institute of Forest, Snow, and Landscapes (WSL) and INTAS project no. 01-0052. |
