Resumo: Great part of the biodiversity of the ecosystem of tropical forests is being lost even before we have full knowledge of its natural wealth, making it important perform studies that can provide knowledge and the maintenance of its structure, besides making possible the exploration of its products, goods and/or services in a planned and rational form, guaranteeing the continuous flow of these resources. The general objective of this study was to use the De Liocourt quotient in the evaluation of the diametric distribution in fragments of Ombrophylous Forest located in the city of Catende, Pernambuco state - Brazil, having as specific objectives: to describe the diametric structure of the fragments and the species of greater importance using the Value of Importance Index (VI); and to evaluate the degradation and the state of succession of the studied areas. The diametric distribution revealed uneven-aged forests as the diametric curve of distribution resembled a reverse J-shape. The values of basal area in the fragments were of 23.6 and 20.9 m2.ha-1, for Mata das Caldeiras and Mata das Galinhas. The fragments were, on average, in the secondary period of succession. Some species presented difficulties in the rate of recruitment, which could lead to the extinguishing of some species in the future. Species, such as Tapirira guianensis Aubl., Dialium guianense (Aubl.) Sandwith and Brosimum discolor Schott, demonstrated a distinct diametric structure among the fragments. The species Plathymenia foliolosa Benth. presented accented discontinuities in the diametric structure in both areas.

Dessa forma, o objetivo deste trabalho foi utilizar o quociente de De Liocourt na avaliação da distribuição diamétrica em fragmentos de Floresta Ombrófila localizados no município de Catende, Zona da Mata Sul do estado de Pernambuco, visando a descrever a estrutura diamétrica dos fragmentos estudados pelo seu Índice de Valor de Importância (IVI), bem como avaliar a degradação e o estado sucessional das áreas. A distribuição diamétrica comportou-se como o esperado para florestas inequiâneas, ou seja, curva de distribuição diamétrica assemelhando-se a um J-invertido. Os valores de área basal nos fragmentos foram de 23,6m2.ha-1, para a Mata das Caldeiras e de 20,9 m2.ha-1 para a Mata das Galinhas. Os fragmentos pesquisados encontram-se em estágio médio de sucessão. Algumas espécies apresentaram dificuldades na taxa de recrutamento, podendo gerar futuramente a sua extinção. Espécies como: Tapirira guianensis Aubl., Dialium guianense (Aubl.) Sandwith e Brosimum discolor Schott, demonstraram estrutura diamétrica distinta entre os fragmentos. A espécie Plathymenia foliolosa Benth. apresentou descontinuidade acentuada na estrutura diamétrica em ambas as áreas.Universidade Federal de Santa Maria2010-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/185410.5902/198050981854Ciência Florestal; Vol. 20 No. 2 (2010); 307-319Ciência Florestal; v. 20 n. 2 (2010); 307-3191980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1854/1199Alves Junior, Francisco TarcísioFerreira, Rinaldo Luiz CaracioloSilva, José Antônio Aleixo daMarangon, Luiz CarlosCosta Junior, Roberto FelixSilva, Shirley de Oliveirainfo:eu-repo/semantics/openAccess2017-05-05T14:08:28Zoai:ojs.pkp.sfu.ca:article/1854Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-05T14:08:28Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
