Resumo: This study aimed to test volumetric models and check the the efficiency of three methods to estimate the wood volume in Eucalyptus urophylla plantation, managed under regime of high forest and coppice, on a property located in the county of Vitória da Conquista, Bahia. It was carried out rigorous measurements scaled trees to obtain the volume to adjust seven volumetric models. The best models were selected using the score pondered value of the statistical parameters (VP). The volumes obtained by three methods (form factor, form quotient and adjusted models) were compared to the volume obtained in the scaling. The models of Schumacher e Hall (log) and Spurr were the more indicated to estimate the volume of stands in both management conditions. The volume obtained from the two best adjusted models resulted in estimates closer to the real volume when compared to the volumes estimated by form factor and the form quotient.

Foi realizada cubagem rigorosa de árvores para obtenção do volume individual, e com os dados foram ajustados sete modelos volumétricos. Os melhores modelos foram selecionados com base no critério de seleção do valor ponderado dos escores dos parâmetros estatísticos (VP). Os volumes obtidos por meio dos três métodos (fator de forma, quociente de forma e modelos ajustados) foram comparados ao volume obtido na cubagem. O modelo de Schumacher e Hall logaritmizado e de Spurr foram os mais indicados para estimar o volume dos povoamentos nas duas condições de manejo. O volume obtido a partir dos dois melhores modelos ajustados resultou em estimativas mais próximas do volume real quando comparados aos volumes estimados pelo fator de forma e quociente de forma.Embrapa Florestas2011-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/29410.4336/2011.pfb.31.68.309Pesquisa Florestal Brasileira; v. 31 n. 68 (2011): out./dez., Florestas Energéticas; 309Pesquisa Florestal Brasileira; Vol. 31 No. 68 (2011): out./dez., Florestas Energéticas; 3091983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/294/230Copyright (c) 2011 Gileno Brito de Azevedo, Glauce Taís de Oliveira Sousa, Patrícia Anjos Bittencourt Barreto, Valdemiro Conceição Júniorhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessAzevedo, Gileno Brito deSousa, Glauce Taís de OliveiraBarreto, Patrícia Anjos BittencourtConceição Júnior, Valdemiro2021-03-19T21:56:12Zoai:pfb.cnpf.embrapa.br/pfb:article/294Revistahttps://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:2021-03-19T21:56:12Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
