Роль климатических изменений в формировании потоков С02 на верховом болоте

A process-based model (Forest-DNDC) was applied for modeling impacts of climate change on carbon dioxide fluxes from a peat bog in European Russia. At first, Forest-DNDC was tested against carbon dioxide (CO2) fluxes measured by the eddy covariance method on an ombrotrophic bog in region of southern taiga (56°N 33°E). The results from the tests showed that Forest-DNDC was capable of quantifying CO2 fluxes from the bog ecosystem. The validated model was then utilized to estimate how climate changes could affect the C dynamics in the bogs under several assumed temperaturehydrology scenarios. The modeling study reported in this paper implicated that the bog ecosystems could become a significant source of atmospheric CO2 under certain temperature and water table changes in future.
