Resumo: A quantitative approach of predicting the growth and yield of natural forests is described and applied. The method proposed aimed at helping the forest manager in decision making concerning the choice of an appropriate cutting cycle. The approach is based upon the transition matrix model. The data used in the simulation model constructed in this study came from a natural forest in Japan  remeasured  during  10  years. The  parameters  necessary for implementation of the method are: the transition matrix of diameter classes, mortality and recruitment estimates for the forest under natural condition and open canopy, and the acceleration of growth rate due to human interference in the stand. The application of the model is demonstrate showing its potential utilization in simulating the effect of different cutting intensities. It was concluded that the model proposed might be a valuable tool for the manager to predict the growth and cutting cycle of logged uneven-aged forests.

É descrito e demonstrado um método quantitativo para auxiliar ao manejador na tomada de decisão quando cortes periódicos são efetuados em povoamentos florestais ineqüiâneos. O método utiliza matriz de transição. Os dados utilizados na construção do simulador são de uma floresta natural do Japão, remedida por 10 anos. Os parâmetros necessários à aplicação do método são a matriz de transição de mudança nas freqüências por classe diamétrica, estimativas de mortalidade natural e por danos, estimativas de aumento de recrutamento com a abertura de dossel e a taxa estimada de aceleração no crescimento provocado por interferências no povoamento. Um exemplo de aplicação do modelo proposto é mostrado, apresentando um cenário das possibilidades de simulação sob diferentes intensidades de corte. Concluiu-se que o modelo proposto é potencialmente um instrumento valioso para o manejador, uma vez que o crescimento e o ciclo de corte de povoamentos florestais ineqüiâneos podem ser preditos.Universidade Federal de Santa Maria1996-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32610.5902/19805098326Ciência Florestal; Vol. 6 No. 1 (1996); 65-78Ciência Florestal; v. 6 n. 1 (1996); 65-781980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/326/194Sanquetta, Carlos RobertoBrena, Doádi AntônioAngelo, HumbertoMendes, Jefferson Buenoinfo:eu-repo/semantics/openAccess2017-06-14T13:15:59Zoai:ojs.pkp.sfu.ca:article/326Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-14T13:15:59Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
