Ecosystem, open thermodynamic system. The oak forest of Virelles-Blaimont.
An attempt is made to apply thermodynamics of irreversible processes to a forest ecosystem. It is assumed to consist of two open sub-systems with chemical reactions (living organisms and abiotic environment) included in one closed system. Entropy flow and entropy production are considered taking into account entropy calculation of incoming and outgoing radiant energy. Some figures are given for the oak mixed forest of Virelles-Blaimont for one vegetation period. Estimated values are calculated for the whole biospheric-atmospheric system.
