Resumo: http://dx.doi.org/10.5902/198050988446The fixed carbon concept is normally related to the idea of storing carbon in forest soil and other vegetations type. This research aimed the modeling of total above ground organic carbon and also for the firewood component by unit of area fixed in Mimosa scabrella stands in the metropolitan region of Curitiba. The database came from 272 temporary sample plots with ages ranging from 3 to 18 years. It was tested 21 traditional models: 10 arithmetic ones and 11 logarithmic ones; it was also developed models by Stepwise process from a correlation matrix. The equation of best performance was chosen based on R²aj, Syx%, F value and on graphic analysis of residuals. A simple linear correlation between the used variables differed from those traditionally found results for volume of stands. This result was also observed in the fitting of mathematical models by stepwise, in which the variable average height didn’t compose any adjusted model. Although efficient, selected traditional equations were less accurate than the equations adjusted by stepwise, reinforcing the importance and improving that this method represents to modeling studies.

A presente pesquisa objetivou a modelagem do carbono orgânico total da parte aérea e da lenha por unidade de área fixada em povoamentos de bracatinga (Mimosa scabrella Bentham) na região metropolitana de Curitiba. Os dados são provenientes de 272 parcelas temporárias com idades variando de 3 a 18 anos. Foram testados 21 modelos tradicionais: 10 aritméticos e 11 logarítmicos; foram também desenvolvidos modelos pelo processo Stepwise a partir de uma matriz de correlação. As equações ajustadas foram comparadas pelo coeficiente de determinação ajustado (R²aj), erro padrão da estimativa percentual (Syx%), teste F e distribuição gráfica de resíduos. A correlação linear simples entre as variáveis utilizadas diferenciou-se daqueles resultados tradicionalmente encontrados para o volume dos povoamentos. Este resultado foi também constatado no ajuste dos modelos matemáticos por Stepwise, nos quais, a variável altura total média não compôs nenhum dos modelos ajustados. Apesar de eficientes, as equações tradicionais selecionadas mostraram-se menos acuradas que as equações ajustadas por Stepwise, reforçando a importância e a melhoria que este método representa para estudos de modelagem.Universidade Federal de Santa Maria2013-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/844610.5902/198050988446Ciência Florestal; Vol. 23 No. 1 (2013); 117-127Ciência Florestal; v. 23 n. 1 (2013); 117-1271980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/8446/pdfSouza, Ronan Felipe deMachado, Sebastião do AmaralFilho, Afonso FigueiredoKoehler, Henrique Soaresinfo:eu-repo/semantics/openAccess2017-04-17T18:32:33Zoai:ojs.pkp.sfu.ca:article/8446Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T18:32:33Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
