T. V. Chernenkova, Yu. N. Bochkarev, M. Fridrich, T. Boettgger The Influence of Natural-Anthropogenic Factors on Radial Increment of Trees on Kola Peninsula // Forest Science (Lesovedenie). 2012. No 4. С.3-15. The dynamics of the radial increment of pine (Pinus sylvestris L.) and spruce (Picea obovata Ledeb.) trees at the northern limit of their distribution was studied on Kola Peninsula. The relation between the radial tree increment and a set of environmental factors, and the contribution of individual environmental factors were revealed. Statistically significant dependences of the tree productivity on the pollution level, relief and climatic conditions were found, as well as the significant relationship between the tree increment and industrial waste volumes. The effect of technogenic loads on trees is related to the their species and position of trees on the upland slopes. The different relations of fluctuations in the tree increment of different frequency levels (longwave - 50 years, midwave - 30 years, and shortwave - interannual) with climatic characteristics were found. Dendrochronological methods, pine, spruce, Kola north, air pollution, heavy metals, annual increment, climate, landscape factors.. |
