Аннотация:Biotic cycling in ecosystems consists of live organic matter production and dead
organic matter destruction. The latter is accompanied by the emission of greenhouse gases into
the atmosphere. In peatland landscapes, additional conditions are imposed due to the presence
of a water table depth (WTD), under which the destruction is anaerobic with methane
generation, while above the WTD it is aerobic, and part of the diffusing methane is consumed
by the methanotrophic bacteria. Hence, due to the complexity of heat and water transfer
processes in the peat deposit and the nonlinearity of biological turnover, it is necessary to make
a combination of their models. The COmplex Model of BOg LAndscapes (COMBOLA) is a
set of dynamic models of carbon and nitrogen turnover, net ecosystem exchange, water
balance, heat and water transport, generation and transfer of CO 2 and CH 4 in a peat deposit on
annual, seasonal, and daily time scales. The main component includes a series of biotic
turnover models – from a mass-balance equation on an annual time scale to a NEE dynamics
model on a daily one. Biotic turnover can be represented by a single carbon cycle, a single
nitrogen cycle or both. Another important component of the COMBOLA system is a one-
dimensional vertical model of heat-water-gas exchange in a peat deposit. Thus, a number of
interconnected modules constitute an integrated mathematical model of peatland landscapes
adapted to any given initial information.
