Net Ecosystem Production of Boreal Larch Ecosystems on the Yenisei Transect
Abstract The study was carried out in the Turukhansk Research Station of Yenisei Transect ($ 65^{°} $$ 46^{′} $N, $ 89^{°} $$ 25^{′} $E). Larch (Larix gmelinii (Rupr.) Rupr.) is the dominant overstory tree species. The research has been conducted on four permanent test plots in same-age mature (110-year old) and overmature (380-year old) post-fire larch stands of green moss and lichen groups of forest type. Carbon cycle parameters were assessed based on a biometric method. Quantitative analysis of carbon pools and fluxes shows that net ecosystem production of north taiga larch stands averages 32% of net primary production. Sink of atmospheric $ CO_{2} $ makes 1.22 and 0.74 t C $ ha^{− 1} $ $ year^{− 1} $ for mature and overmature green moss larch stands, and 0.65 and 0.35 t C $ ha^{− 1} $ $ year^{− 1} $ for lichen type. Net carbon sink in the tree layer make up 9% of net primary production carbon, ground vegetation – 15%, and dead plant residues accumulation – 8% of atmospheric carbon uptake via photosynthesis.
