Resumo: This research aims to adjust and select models to quanti- fy the volume of the tree vegetation and its total and com- partmental biomass, in a ‘cerradão’ (forest savanna), in the municipality of Palmas, Tocantins, Brazil. A forestry invento- ry was performed in an area of 10.15ha, divided in sampling plots measuring 400m 2 , in which all living and dead standing trees ≥5cm DBH were sampled and identified, with a 20% er- ror margin. The trees were cubed using the Smalian meth- od and 84 of them were weighted. After obtaining the green mass by compartment, samples were removed in order to es- timate the dry biomass. Mathematical models were adjusted to estimate total volume/biomass per unit area as well as by compartment. The Schumacher and Hall model was chosen. After processing, the inventory error was within the admissi- ble margin. Volume and total stoked biomass by hectare were 126.71m3·ha -1 and 61.67Mg·ha -1 . For the bole and crown com- partments the values were 79.23 and 47.17m3·ha -1 for volume and 29.70 and 31.98Mg·ha -1 for biomass. Dead trees summed 6.70% of the volume and 7.00% of the biomass, while leaves contributed with 7.3% of the total biomass. Bark summed 11.50% of the volume and 21.00% of the biomass. Volume and biomass stocks on the studied biome, when compared to oth- ers types of ‘cerradões’, are higher than those found on sa- vannan formations.

Se realizó un inventario forestal en un área de 10,15ha, mediante un muestreo sistemático con parcelas de 400m2, donde fueron muestreados e identificados todos los árboles en pie vivos y muertos con DAP≥5cm, con un error admisible del 20%. Fue- ron cubicados 84 árboles por el método Smalian y luego pe- sados. Después de obtener la masa verde por compartimientos se tomaron muestras del material a fin de obtener la biomasa seca. Para estimar el total de volumen/biomasa por unidad de área y por compartimientos, se realizó un ajuste de los mo- delos matemáticos. Se seleccionó el modelo de Schumacher y Hall. Después de realizar el inventario, el error estuvo den- tro del valor admitido. El volumen y la biomasa total aérea almacenados por hectárea fueron 126,71m3·ha -1 y 61,67Mg·ha -1 , respectivamente. Para los compartimientos fuste y copa, los valores para el volumen fueron 79,23 y 47,17m3·ha -1 y para la biomasa 29,7 y 31,98Mg·ha -1 . Los árboles muertos contribuye- ron con 6,70% del volumen y 7% de la biomasa; las hojas con el 7,30% de la biomasa total. La corteza contribuyó con 11,5% del volumen y 21% de la biomasa. El stock de volumen y bio- masa encontrado en el área de estudio, comparado con otros ‘cerradões’ y diferentes tipos de vegetación de cerrado, es más alto que los encontrados en las formaciones de sabana.Objetivou-se ajustar e selecionar modelos para quanti- ficar o volume e a biomassa total e por compartimento na vegetação arbórea em um cerradão, no Município de Pal- mas, Tocantins, Brasil. Foi realizado um inventário florestal em área de 10,15ha, utilizando amostragem sistemática com parcelas de 400m2, onde foram amostradas e identificadas todas as árvores vivas e mortas em pé, com DAP≥5cm para um erro admissível de 20%. Foram cubadas pelo método de Smalian e posteriormente pesadas 84 árvores. Obtido a mas- sa verde por compartimentos, foram retiradas amostras do material visando à obtenção da biomassa seca. Para a esti- mativa do volume/biomassa total, e por compartimento por unidade de área ajustou modelos matemáticos. O modelo de Schumacher e Hall foi o selecionado. Quando processado o erro do inventário ficou dentro do admitido. A quantida- de de volume e biomassa total aéreo estocado por hectares foram 126,71m3·ha -1 e 61,67Mg·ha -1 . Quando analisados pelos compartimentos fuste e copa, estes valores para o volume foi 79,23 e 47,17m3·ha -1 e 29,70 e 31,98Mg·ha -1 para a biomassa. As árvores mortas contribuíram com 6,7% do volume e 7% da biomassa, as folhas com 7,30% da biomassa total. As cas- cas contribuem com 11,50% do volume e 21,00 % da biomas- sa. O estoque em volume e biomassa no cerradão estudado, quando comparado a outros cerradões e distintos tipos de ve- getação do cerrado, encontra-se superior ao encontrado nas formações savânicas.Interciencia2019-03-01T13:48:50Z2019-03-01T13:48:50Z2017-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf22447776https://www.researchgate.net/publication/313382709http://www.locus.ufv.br/handle/123456789/23781engVolume 42, Number 01, Pages 21- 27, January 2017Rezende, Alba ValériaMiguel, Eder PereiraPereira, Reginaldo SergioAzevedo, Gileno Brito deMota, Fabrícia Conceição MenezSouza, Álvaro Nogueira deJoaquim, Maísa Santosinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:30:15Zoai:locus.ufv.br:123456789/23781Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:30:15LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
