Resumo: This work aimed to evaluate the use of traditional models, profile and relative height method, for estimating the commercial volume of Anadenanthera colubrina (Vell.) Brenan. Data were obtained from scaling of separate lengths of the stem of 22 trees, using Smalian’s method. Tree stems were measured 0.1m, 0.30m, 0.70m, 1.0m, 1.30m above the ground and then every 1m. For purposes of method assessment and comparison, statistics were used that include percent standard error, bias, standard deviation of differences, in addition to graphic interpretation of residuals. Assessments showed that Stoate’s model is the most accurate, followed by Schumacher’s model. They also showed that the linearized Schumacher’s model reduced accuracy by an average 0.32%and that the relative height method was biased in this study.

Brenan. Os dados foram obtidos da cubagem rigorosa de 22 árvores através do método de Smalian. Os fustes das árvores foram medidos a 0,1m; 0,30m; 0,70m; 1,0m; 1,30m e posteriormente de 1 em 1m. Para fins de avaliação e comparação dos métodos, foram aplicadas estatísticas de: Erro padrão percentual, Bias, Desvio Padrão das Diferenças, além da interpretação gráfica dos resíduos. Com base nestas avaliações pôde-se concluir que o modelo de Stoate é o mais preciso, seguido pelo modelo de Schumacher. Conclui-se também que a linearização do modelo de Schumacher reduziu sua precisão 0,32% em média e que o método da altura relativa foi tendencioso neste estudo.Universidade Federal de Lavras (UFLA)2015-05-142017-08-01T20:17:03Z2017-08-01T20:17:03Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfCARVALHO, S. de P.
