Resumo: | This study aimed to fit mathematical models for estimating commercial volume with bark for species of an Upland Dense Rain Forest located in southern of the state of Roraima, Brazil. It was cubed by Smalian method an amount of 122 trees of 18 species with diameter at breast height (DBH) higher than 50 cm. Nine models were adjusted by least squares methods, and selected on the basis of the adjusted determination coefficient, standard error in percentage, F value and graphical analysis of residuals distribution. Schumacher-Hall model was selected. Kopezki-Gherardt model can be used when data from commercial height are not used. |

Foram abatidas e cubadas pelo método de Smalian 122 árvores de 18 espécies com diâmetro à altura do peito maior do que 50 cm. Foram testados nove modelos, ajustados pelos métodos dos mínimos quadrados, e selecionados em função do coeficiente de determinação ajustado, do erro padrão de estimativa em porcentagem, do valor de F calculado e da análise gráfica da distribuição dos resíduos. Recomendou-se o modelo de Schumacher-Hall. O modelo de Kopezki-Gherardt pode ser empregado, quando não se utilizar dados de altura comercial.Embrapa Florestas2015-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/73810.4336/2015.pfb.35.82.738Pesquisa Florestal Brasileira; v. 35 n. 82 (2015): abr./jun.; 111-117Pesquisa Florestal Brasileira; Vol. 35 No. 82 (2015): abr./jun.; 111-1171983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/738/417Copyright (c) 2015 Helio Tonini, Renato Alves Borgeshttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessTonini, HelioBorges, Renato Alves2017-04-28T12:44:45Zoai:pfb.cnpf.embrapa.br/pfb:article/738Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:44:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
