Resumo: | The relative height method allows the characterization of stem profile without meeding sample trees to upper diameter measurements. The analytical geometry is applied on the diameter taken on 0,3 meters and on hr = (h-2)/2, as well as dbh and total height (h), making possible the measurement of these variables, simultaneously, with others measured on the permanent sampling in forest inventory. This study evaluated some alternatives in characterizing the stem profile by using analytical geometry, comparing it to the original method according Andrade (2001). It was concluded that the use of relative diameters to dbh showed better results in regression analysis to generate straight line angular coefficient. Also, to obtain better accuracy, it is more adequate to implement the relative height method using all trees inside the inventory sample unit. |

Emprega-se geometria analítica nas variáveis obtidas partindo de diâmetros tomados a 0,3 metros do terreno e em hr = (h-2)/2, além de d1,3 e h, o que viabiliza a medição destas, simultaneamente, com as demais variáveis mensuradas nas parcelas de inventário florestal. Neste trabalho, foram avaliadas algumas opções para caracterização do perfil do tronco empregando geometria analítica, comparando-se com o seu uso original conforme Andrade (2001). Concluiu-se que o uso de diâmetros relativos ao dap apresentaram melhores resultados para empregar a análise de regressão, a fim de se gerar coeficientes angulares da reta. Também, na expectativa de melhor acurácia, é mais adequado empregar o método da altura relativa utilizando todas as árvores delimitadas pelas parcelas do inventário.Universidade Federal de Santa Maria2006-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/191010.5902/198050981910Ciência Florestal; Vol. 16 No. 3 (2006); 303-317Ciência Florestal; v. 16 n. 3 (2006); 303-3171980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1910/1154Andrade, Valdir Carlos Lima deCalegario, NatalinoScolforo, José Roberto Soaresinfo:eu-repo/semantics/openAccess2017-05-15T13:33:33Zoai:ojs.pkp.sfu.ca:article/1910Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T13:33:33Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |

The analytical geometry is applied on the diameter taken on 0,3 meters and on hr = (h-2)/2, as well as dbh and total height (h), making possible the measurement of these variables, simultaneously, with others measured on the permanent sampling in forest inventory. This study evaluated some alternatives in characterizing the stem profile by using analytical geometry, comparing it to the original method according Andrade (2001). It was concluded that the use of relative diameters to dbh showed better results in regression analysis to generate straight line angular coefficient. Also, to obtain better accuracy, it is more adequate to implement the relative height method using all trees inside the inventory sample unit. |
