Abstract
Studying the dynamics of carbon stocks in wetland ecosystems will allow us to more accurately assess the contribution of wetlands to global climate change. This work proposes a zero-dimensional mathematical model that describes the carbon dynamics of a local (at the watershed scale) wetland ecosystem, taking the ambient temperature into account. The proposed model identifies two carbon reservoirs: plant phytomass and organic carbon in mortmass. The main processes of the model include photosynthesis, respiration, phytomass die-off, and carbon leaching by groundwater. Numerical experiments were carried out to show how changes in ambient temperature affect the dynamics of carbon stocks in wetland ecosystems.
