Abstract
GALEANA-PIZANA, José Mauricio; ORDONEZ-DIAZ, José Antonio Benjamín and CORONA-ROMERO, Nirani. Estimation of carbon content in the Magdalena River basin, Mexico. Madera bosques [online]. 2013, vol.19, n.1, pp.53-69. ISSN 2448-7597.
Carbon content of aboveground biomass of six types of vegetation cover in the Magdalena River basin, located in the conservation land in the Mexico City, was estimated. Hence, a map of cover vegetation and land use to the study area was made; a hierarchical stratified sampling design with distribution systematic with a mesh of sampling sites equidistant of 550 meters was used for field work. The method used for field data collection was based on a nested design, with an intensity of sample of 0,64%. There were generated 52 sites of 3000 m2. The vegetation cover that showed the highest amount of carbon stored corresponds to the forest of the the Abies religiosa closed with 163 Mg C ha1 in average; followed by the Abies religiosa - Pinus hartwegii closed with 107 Mg C ha1, and Abies religiosa opened with 95 Mg C ha1; about the covers of Pinus sp., Pinus hartwegii closed with 47 Mg C ha1; Pinus hartwegii - Abies religiosa closed with 39 Mg C ha1 and Pinus hartwegii opened with 21 Mg C ha-1.
Keywords : Abies religiosa; above ground biomass; forest; diametrical structure; Pinus hartwegii.
