چکیده
O estudo foi realizado na Reserva Florestal de Mecubúri, em Moçambiquee, visando avaliar os efeitos das atividades antrópicas sobre a cobertura florestal. Áreas queimada, agrícola e exploração florestal foram comparadas com uma área controle termos composição fitossociologia. Em cada área, estabelecidas, maneira sistemática, parcelas quadrangulares 20 x m, distantes m da outra, sendo o levantamento vegetação adulta regeneração. Foram determinados índices similaridade, diversidade riqueza. Os resultados indicaram existir dissimilaridade entre as áreas, que espécies Julbernardia globiflora, Diplorhynchus condylocarpon, Brachystegia utilis, Millettia stuhlmannii, Afzelia quanzensis, Burkea africana Cussonia arborea destacaram-se abundância, frequência, dominância, Índice Valor Importância (IVI) maior número árvores por hectare encontrado menor agrícola. Com base no índice dispersão Morisita, parte distribui-se forma aleatória agrupada. A distribuição diamétrica seguiu padrão J-invertido, característico florestas naturais. As práticas queimadas, agricultura contribuem redução Mecubúri. Palavras-chave: fitossociologia; conservação; desmatamento. The effect of anthropic activities on forest coverage in the Mecubúri Forest Reserve, Mozambique ABSTRACT: study was carried out Mozambique, with purpose evaluating effects human cover. Burning, agricultural and logging areas were compared control area terms composition phytosociology. In each systematically established quadrangular plots, apart from other, which survey adult vegetation regeneration. similarity, diversity richness indices determined. results showed that there is dissimilarity between species stood abundance, frequency, dominance, Importance Value Index largest number trees per found area, smallest area. Based Morisita dispersion index, most have random clustered distribution. diametric structure followed inverted-j, typical natural forests. agriculture contribute to reduction cover Reserve. Keywords: phytosociology; conservation; deforestation.
