Effects of abiotic factors on the parameters of the CO2/H2O exchange in Betula pendula Roth, Populus tremula L., Alnus incana (L.) Moench and Pinus sylvestris L. trees in the middle-taiga subzone of southern Karelia was studied. Carbon and water exchange of woody plants were studied using the portable photosynthesis system LI-COR 6400ХТ (LI-COR Inc., USA) and the pressure chamber Plant Moisture Vessel SKPM 1400 (Skye Instruments Ltd., UK). The results of provided leaf photosynthesis, respiration and stomatal conductance measurements were used in the process-based Mixfor-SVAT model (Olchev et al., 2017) to derive the possible response of CO2/H2O budgets of Karelian forest ecosystems to future climatic changes.
