Paper Abstract

The problem of CO2 balance is a basic in the biosphere study and in the prediction of consequences of the global climate change due to anthropogenous impacts. The growing mires are the unique ecosystems among the terrestrial biosystems capable to fix the atmospheric CO2 for a long period. The CO2 emission from peatlands into the atmosphere is caused by mineralization processes of organic substances taking place due to drainage. The quantity of carbon dioxide emission from the peatland or from the peat deposits surface is an integral indicator of the transforming processes intensity in the peat. Different physical-chemical methods are used in the CO2-gas-analysis. The aim of this work is a comparison of the hemosorption and optoacoustic gas- analysis methods. The outlines of the methods and their characteristics is also presented. The intercalibration was carried out under maximum possible identical conditions of the experiment. The CO2 concentration and CO2 emission kinetics at mineralization process of peat were measured simultaneously by both methods. It was shown that the results are in good agreement.
