Effect of Fires on the Functioning of Phytocenoses of Peat Bogs in the Middle-Amur Lowland

The dynamics and structure of the phytomass and production of an undisturbed mesotrophic dwarf shrub-sphagnum phytocenosis and one burned by fire have been compared. The net primary production (NPP) of both sites of phytocenoses in the postpyrogenic period is estimated by direct field determination of the productivity parameters, and C emission from the fire is assessed. The obtained data on emission (0.7 kg/m(2)) differ from the results obtained in the peatlands of western Canada (3.2 kg/m(2)).
