Abstract


A floristic and structural composition studies of Kponyo forest, a forest close to the hunting field of Bili Uélé, was carried out with the aim of knowing the variability of the forest types through the evaluation of the parameters such as abundance, taxa predominance, basal area, biodiversity indices and the mode of space distribution of the dominant species in each inspected site. The method of subplot made it possible to sample two hectares (8 pieces of 50 m X 50 m). On the whole, 636 individuals belonging to 173 species and 66 families were inventoried. The species Gilbertiodendron dewevrei abounds the hydromorph land forest while the species Garcinia epunctata abounds the firm land forest. The Fabaceae family dominates this florule. Basal area average is 28,14m2/ha. The analysis according to the K repley® function of Gilbertiodendron dewevrei and Garcinia epunctata shows a random distribution within the settlement.

Abstract: (french)


Une étude de la composition floristique et structurale de la forêt de Kponyo, une forêt proche du domaine de chasse de Bili Uélé, a été réalisée dans le but de connaitre la variabilité de types forestiers au travers l’évaluation des paramètres tels que l’abondance, la dominance des taxons, la surface terrière, les indices de diversité et le mode de répartition spatiale des espèces dominantes dans chaque site inspecté. La méthode de placeau a permis d’échantillonner deux hectares (8 parcelles de 50 m x 50 m). Au total, 636 individus regroupés en 173 espèces et 66 familles ont été inventoriés. L’espèce Gilbertiodendron dewevrei abonde la forêt hydro-morphe tandis que l’espèce Garcinia epunctata abonde la forêt sur terre ferme. La famille de Fabaceae domine cette florule. La surface terrière moyenne est de 28,14m2/ha. L’analyse selon la fonction K repley® des Gilbertiodendron dewevrei et Garcinia epunctata montre une répartition aléatoire au sein du peuplement.
