Gitarsky Carbon Emission in the Course of Slash Decomposition in a Southern Taiga Spruce Forest // Forest Science (Lesovedenie). 2012. No 5. С.44-49. The formation of dead wood stock and atmospheric flux of carbon dioxide (CO2) from its subsequent decomposition were investigated in the mature spruce forest of the Valday terrain. The standing dead trees and woody debris composed 45.4% of the entire (live and dead) volumetric stock in the stand, dominated by the debris of the third rate of the decomposition (73.2). In the summer time, the CO2 flux from the decomposition of woody debris was estimated as 10.02 kg C ha-1day-1. The woody debris of the third rate of the decomposition contribured to 95% of the flux. The woody debris decomposition rate becomes an integrated measure of the CO2 emission intensity. Spruce stand, carbon dioxide, decomposition of wood debris, dead wood.. |
