Resumo: | To better understand the dynamics of the forest in relation to its structure, it is important to conduct studies on communities that compose them. The aim of the work was the phytosociological analysis of fragments of forest on the campus of the Federal University of Amapá. For the study, 40 permanent plots systematically 250m² were installed. All trees with (CAP) ≥ 10 cm were sampled. The botanical material was identified in the Herbarium of the Federal University of Amapá, following the classification system APG III. The horizontal parameters analyzed were: Density, Dominance, Frequency, Importance Value, Diversity and Distribution diameter and Space. The specie with the highest importance value was Enterolobium schomburgkii (28.76 %), but the most common in the area was the Protium guacayanum species who appeared in almost all plots of the study area. The largest of the CAP was found of the species Byrsonima aerugo Sagot, the family Malpighiaceae, measuring 220 cm. In the floristic composition survey, 2,431 individuals were sampled and identified about 90 species belonging to 40 families. The family that had the greatest number of individuals was the Fabaceae (496). Regarding the distribution diametric the class 7 and 9 showed absence of individuals in relation to the most sought-after species of commercial value. The spatial distribution of the species was aggregate. Slightly more than 50 % of young individuals compete for abiotic factors, given that the vegetation is in the process of formation of the forest fragments than are restructuring.Keyword: Phytosociology; abiotic; species; classes. |

O objetivo do trabalho foi realizar a análise fitossociológica dos fragmentos de mata existentes no Câmpus da Universidade Federal do Amapá. Para o estudo, foram instaladas sistematicamente 40 parcelas permanentes de 250m². Foram amostrados todos os indivíduos arbóreos com (CAP) ≥ 10 cm. O material botânico coletado foi identificado no Herbário da Universidade Federal do Amapá, seguindo Sistema de classificação APG III. Foram analisados os seguintes parâmetros horizontais: Densidade, Dominância, Frequência, Valor de Importância, Diversidade e Distribuição Diamétrica e Espacial. A espécie que apresentou maior valor de importância foi a Enterolobium schomburgkii (28,76%), porém a mais frequente na área foi a espécie Protium guacayanum que apareceu em quase todas as parcelas da área de estudo. O maior CAP encontrado foi da espécie Byrsonima aerugo Sagot, da família Malpighiaceae, medindo 220 cm. No levantamento da composição florística, foram amostradas 2.431 indivíduos, e identificados cerca de 90 espécies pertencentes a 40 famílias. A família que apresentou maior número de indivíduos foi a Fabaceae (496). Em relação a distribuição diamétrica a classe 7 e 9 apresentaram ausência de indivíduos em relação às espécies mais procuradas de valor comercial. A distribuição espacial demonstrou como sendo agregada. Um pouco mais de 50 % dos indivíduos jovens competem de igual frequência por fatores abióticos, tendo em vista que a vegetação esta em processo de formação e os fragmentos florestais estão se reestruturando.Palavra-chave: Fitossociologia, abióticos, espécie, classes.
