| description | The total aboveground biomass (B) of terrestrial ecosystems has carbon stocks of high importance for mitigation actions of climate chan¬ge through mechanisms such as REDD+. To be able to access possible financial compensation to avoid deforestation or degradation of forests, in addition to conservation, increase of stocks and sustainable forest management, it is necessary to evaluate biomass and carbon estimation errors, which are generally associated with the allometric model used. The common allometric models, relationships between normal diameter (D) and total height (H) with biomass, use statistical techniques that do not take advantage of the relations between the exponents of the models, nor the relationships between the constants and exponents of each model. This work presents a generalized theoretical framework applicable at the level of monospecies and multispecies, which is applied to a set of 684 measurements of D, H and B, from 23 databases of individual species. The results obtained, when all the parameters were available, were practically without error. In the cases of lack of information of a parameter, the estimations made under different approximations showed estimation errors comparable with those obtained by the classical methods of development of generalized allometric models. The methodological process presented serves as the basis for the proposal of changes in the allometric information generation approaches, to simplify and reduce errors in estimating biomass and carbon. |

Los ecosistemas terrestres tienen almacenes en la biomasa aérea (B) de alta importancia para acciones de mitigación del cambio climático a través de mecanismos tales como REDD+. Para obtener posibles compensaciones financieras por evitar deforestar o degradar los bosques, además de la conservación, incrementar los almacenes de carbono y manejo forestal sustentable, es necesario evaluar los errores de estimación de biomasa y carbono, que generalmente están asociados al modelo alométrico usado. Los modelos alométricos sobre las relaciones entre diámetro normal (D) y altura total (H) con la biomasa usan técnicas estadísticas que no aprovechan las relaciones entre los parámetros de los modelos, ni las relaciones entre las constantes y exponentes de cada modelo, por lo que en este trabajo se presenta un marco teórico generalizado aplicable a nivel de monoespecies y multiespecies, el cual fue aplicado a un conjunto de 684 mediciones de D, H y B, provenientes de 23 bases de datos de especies individuales. Los resultados obtenidos, cuando se cuenta con datos, prácticamente no presentaron error cuando se consideraron todos los parámetros. Cuando faltó información de un parámetro, las estimaciones realizadas con diferentes aproximaciones mostraron errores de estimación comparables con los obtenidos por los métodos clásicos de generación de modelos alométricos generalizados. El proceso metodológico desarrollado sirve de base para plantear cambios en los enfoques de generación de información alométrica, para simplificar modelos y para reducir los errores en la estimación de la biomasa y el carbono.
