摘要

The generation of equations of biomass is important because they allow to evaluate the structure and condition of a forest, quantify its productivity, determine the amount of fixed carbon, the fixation rate of CO2, and thus valuate the impact on the mitigation of greenhouse gases. The objective of the present study was to fit allometric equations to quantify the accumulation of biomass (B), carbon (C), and carbon equivalent (CO(2)e) in a mixed plantation of 12 years of age of Pinus devoniana Lindl. and Pin us pseudostrobus Lindl., in Jerecuaro, state of Guanajuato, Mexico. The biomass of each tree, leaves plus branches.(Bhr); stem (Bf) and total (Bt) was calculated using the ratio between dry weight and fresh weight, in 20 trees of each species. Through stem analyses and the Schumacher model the rate of annual increment of B, C and CO(2)e was obtained. Results indicate that the allometric equations efficiently quantify the components of biomass, especially of Bf (R-2>0.85) in P. pseudostrobus, this species showing the highest increments in aboveground biomass. The total aboveground biomass, of 60.2 and 58.4 % was registered in the stem; 39.8 and 41.6 % in the leaves and branches of P devoniana and P pseudostrobus. Values calculated were 39.36 t B ha(-1), 19.68 t C ha(-1) and 72.02 t CO(2)e ha(-1), after 12 years of the establishment of the plantation. According to the Schumacher model, the maximum productivity of aboveground biomass (Bf and Bhr) is reached at 20 years of age, which represents 3.96, 1.98 and 7.27 t ha(-1) year(-1) of B, C and CO(2)e.
