CO2 fluxes at south taiga bog in the European part of Russia in summer

详细

This paper estimates CO₂ emission and net ecosystem exchange (NEE) between the atmosphere and the surface of bog in the south taiga of the European part of Russia for the summer periods of 2013–2015. Flux measurements are carried out by the static chamber method every 7–10 days in three experimental sites with homogenous conditions of soil moisture and vegetation type. Statistically significant differences in CO₂ fluxes and NEE are found between different experimental sites. It is shown that an assessment of the significance of bogs in CO₂ balance with the atmosphere must be made with consideration for the spatial heterogeneity of bogs.
