Resumo: The objectives of this study were: to compare and to apply indices that quantify diversity, equability and similarity in the studied area; to identify possible diversity gradients, and to apply  multivariate analysis to create dendrograms of similarity. The studied area was composed of 20 native forest fragments sited in riparian permanent preservation areas along the basin of São Francisco River, in Minas Gerais. The diversity presented a large variation according to all indices: Shannon: 2,176 to 4,389; Simpson: 0,019 to 0,206; Mixture quotient: 0,029 to 0,166, Equability 0,625 to 0,875. The floristic similarity among fragments using the Jaccard and Simpson quotients formed 5 and 4 floristic groups, respectively, with a cut level of 25%.

A área de estudo compreendeu vinte fragmentos pertencentes às áreas ripárias de preservação permanente na Bacia do Rio São Francisco-MG. Como resultados encontrados, segue que a diversidade dentro da bacia apresentou uma grande variação pelos índices de Shannon: 2,176 a 4,389; Simpson: 0,019 a 0,206; Quociente de mistura de Jentsch: 0,029 a 0,166, Equabilidade 0,625 a 0,875. Ao analisar a similaridade florística entre os fragmentos, pelos quocientes de Jaccard e Sorensen, pode-se observar a formação de cinco e quatro grupos florísticos, respectivamente a um nível de 25% de corte.Universidade Federal de Santa Maria2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/189410.5902/198050981894Ciência Florestal; Vol. 16 No. 2 (2006); 127-144Ciência Florestal; v. 16 n. 2 (2006); 127-1441980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1894/1140Gomide, Lucas RezendeScolforo, Jose Roberto SoaresOliveira, Antônio Donizette deinfo:eu-repo/semantics/openAccess2017-05-15T13:57:07Zoai:ojs.pkp.sfu.ca:article/1894Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T13:57:07Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
