Resumo: | To quantify the stock of commercial timber in forests demands efficient methods, making possible to estimate efficiently and accurately the present and future timber volume. The aim of this work was to adjust the mathematical models used to estimate timber volume, allowing the determination of the timber potential of a region with greater accuracy and lower cost. The study was conducted at Lábrea, State of Amazonas, Brazil in an area of 6,000 ha, inserted in the Project Forest Management Seringal Iracema II. The forest is predominantly dense with emergent trees, also with the occurrence of open forest with bamboo and palms. For the process of adjusting the models to estimate the volume of commercial timber, 141 trees of commercial species were cubed by Smalian method. The equations developed for the Forest Management Project Seringal Iracema II are valid for diameters between 50 cm and 140 cm and for forests with similar structure; to standing trees due to its simplicity and accuracy, the best equation was Kopezki-Gehrardt (V = - 0.6870 + 0.00103 d²); for felling trees or for studies of biomass and carbon stock, the equation indicated is Schumacher-Hall (LnV = -9.5452 + 2.12837 Ln (d) + 0.72209Ln (h)).doi: 10.4336/2010.pfb.30.64.283 |

O objetivo desse trabalho foi ajustar modelos matemáticos, para estimativa de volume comercial de madeira, permitindo a determinação do potencial madeireiro de uma região, com maior precisão e menor custo. O estudo foi realizado no Município de Lábrea, AM, em uma área de 6 mil ha, inserida no Projeto de Manejo Florestal Seringal Iracema II. A floresta é predominantemente densa com árvores emergentes, também com ocorrência de Foresta Aberta com bambu e palmeiras. Foram cubadas pelo método Smalian 141 árvores de diferentes espécies comerciais para a estimativa do volume de madeira comercial. As equações obtidas são válidas para os diâmetros entre 50 cm e 140 cm e para florestas com estrutura semelhante; para árvores em pé, devido a sua simplicidade e precisão, a melhor equação foi a de Kopezki-Gehrardt (V=-0,6870 + 0,00103 d²). Para árvores derrubadas ou para estudos de biomassa e estoque de carbono, a equação indicada foi a de Schumacher-Hall (LnV = -9,5452 + 2,12837 Ln(d) + 0,72209 Ln(hc)). doi: 10.4336/2010.pfb.30.64.283Embrapa Florestas2010-11-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/155Pesquisa Florestal Brasileira; v. 30 n. 64 (2010): out./dez.
