Technical energy costs required for forest cultivation, estimation of C-CO2 fluxes in model experiments with coniferous species of pine Pinus sylvestris L. and leaves species, natural form and gene modified clone of the ordinary aspen tree Populus tremula L., have been analyzed. At plantation cultivation of transgenic aspen clone with nitrogen fertilizers indirect costs of technical energy made up 85 % of total power input. A new three-stage method has been developed for assessing the impact of forests on the CO2 balance in the Earth's atmosphere. The final value of CO2 sink from the atmosphere at afforestation depends on the way wood is used. |
