### Link between Carbon Dioxide Fluxes and Phytomass  
The correlation matrix of the median carbon dioxide fluxes and phytomass stock components in the studied swamp areas was first built in order to determine those phytomass components that are most closely related to carbon dioxide fluxes (R\({}_{\rm eco}\) and GEE) in the context of the parameterization of mathematical models (Table 11). A close relationship (R = \(-\)0.7, \(p\) = 0.05) was found between NEE and mortmass at a depth of 15 cm (M\({}_{15}\)). In addition, a fairly high correlation coefficient (R = 0.6) was found between the mass of the living roots of vascular plants at the same depth (R\({}_{15}\)) and NEE. Other phytomass components showed a weak negative relationship with carbon dioxide fluxes (1R! did not exceed 0.5). There was no linear relationship between net ecosystem exchange (NEE), vascular plant litter mass (Ph\({}_{\rm L}\)), dead rootstock at 15-25 cm (RM\({}_{15,25}\)) and other mortmass at 25 cm (M\({}_{25}\)) (i.e., 1R! did not exceed 0.1). R\({}_{\rm eco}\) directly correlated with vascular plant litter weight (Ph\({}_{\rm L}\); R = 0.9); feedback was found with aboveground moss phytomass (Ph\({}_{\rm M}\); R = \(-\)0.7). The amount of Ph\({}_{\rm L}\) differed significantly between different sites; therefore, the high correlation coefficient probably illustrates not only the significant contribution of litter decomposition to R\({}_{\rm eco}\) but also the rather large spatial variability of Ph\({}_{\rm L}\). On the other hand, the negative relationship between Ph\({}_{\rm M}\) and R\({}_{\rm eco}\) probably indicates the effect of moisture conditions on respiration intensity: with an increase in WTL and, as a result, aboveground moss phytomass, respiration processes slow down due to the formation of anaerobic soil conditions. A fairly close relationship (1R! was found between R\({}_{\rm eco}\) and the aboveground phytomass of vascular plants (Phv), live roots at a depth of 5 cm (R\({}_{5}\)) and dead roots at 5 and 15 cm (RM\({}_{5,15}\)), as well as other mortmass at 25 cm (M\({}_{25}\)). At the same time, there is an inverse relationship between dead phytomass and a direct relationship with living phytomas. \begin{table}

Finally, GEE correlated closely with \(|\)R\(|\)\(\geq\) 0.7 with aboveground vascular plant phytomass (\(\mathrm{Ph_{V}}\)), litter (\(\mathrm{Ph_{L}}\)), and live plant root mass at 15 cm depth (\(\mathrm{R_{15}}\)). \(\mathrm{R_{eco}}\) and GEE were also closely correlated. As GEE increased, \(\mathrm{R_{eco}}\) decreased, and vice versa.
