Resumo: The Amazon forest has suffered the loss of areas facing the advance of deforestation linked to development policies in the region. Thus, the study aimed to study the floristic composition and diversity of forest remnants in the catchment area of the reservoir of the plant hydroelectric of Tucuruí. Had been installed four parcels of 100 m x 100 m (1 ha), divided in 25 sub-parcels of 20 m x 20 m, in each sub-parcel, the individuals with diameter the height of the chest ≥ 10 cm had been registered all the diversity were calculated through the Index Shannon and Equability of Pielou. The floristic similarity was esteem through the indices of Jaccard and Sorensen. For the four inventoried paecels it was found a total of 1.720 individuals, distributed in 49 families, 156 sorts and 305 species. The number of families and species between the samplings varied of 32 the 43 and 76 the 156, respectively. It enters the five more representative families in number of Fabaceae species was present in all, Mimosaceae was enters most representative in three and Sapotaceae, Chrysobalanaceae and Lecythidaceae had been most representative only in sampling III. Sampling III presented the biggest value of diversity (4,40) and sampling I the minor (3,55). It enters the samplings the biggest values of similarity had been registered for samplings I and II and the minors for I and III. The results showed that the remaining studied showed differences regarding the number of families and species, although these are inserted in the same floristic matrix.Keywords: floristic; similarity; diversity.

Desta forma, o trabalho teve como objetivos estudar a composição florística e a diversidade de remanescentes florestais na área de influencia do reservatório da UHE de Tucuruí e analisar seus padrões de semelhanças. Foram instaladas quatro parcelas de100 mx 100 m (1 ha), divididas em 25 sub-parcelas de20 mx20 m, em cada sub-parcela, foram registrados todos os indivíduos com DAP ≥ 10 cm. A diversidade foi calculada através do Índice Shannon e Equabilidade de Pielou. A similaridade foi estimada através dos índices de Jaccard e Sorensen. Para os quatros hectares inventariados foram encontrado um total de 1.720 indivíduos, distribuídos em 49 famílias, 156 gêneros e 305 espécies. O número de famílias e espécies entre as parcelas variou de32 a43, e76 a156, respectivamente. Entre as famílias mais representativas em número de espécies Fabaceae e Mimosaceae apresentaram maior destaque no geral. Sapotaceae, Chrysobalanaceae e Lecythidaceae foram as mais representativas somente na parcela III. A parcela III apresentou o maior valor de diversidade (4,40) e parcela I o menor (3,55). Entre as parcelas os maiores valores de similaridade foram registrados para as I e II e os menores para I e III. Os resultados mostraram que os remanescentes estudados apresentaram diferenças com relação ao número de famílias e espécies, embora estes estejam inseridos na mesma matriz florística.Palavras-chave: florística, similaridade, diversidade.Universidade Federal do AmapáCentrais Elétricas do Norte - EletronorteRosa-Junior, Waldemiro de OliveiraBastos, Maria de Nazaré do Carmodo Amaral, Dario DantasSoares, Cintia da Cunha2015-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/98110.18561/2179-5746/biotaamazonia.v5n2p10-17Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 5, n. 2 (2015); 10-172179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/981/v5n2p10-17.pdfAmazônia;Pará;Brasil;TucuruíLevantamento florístico; Diversidade floríticaDireitos autorais 2015 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-03-29T17:53:10Zoai:ojs.pkp.sfu.ca:article/981Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-03-29T17:53:10Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
