Resumo: | The amazon forest and your different ecosystems - firm land, várzea and igapó - have been being target of intense studies concerning their dioxide carbon drain role and mostlyon the factors that indicate a narrow relationship among feedback processes and the intensification of the climatic changes. Igapó woods, that permanently or good part of year are submerged, also are wellknown for its hostility and difficult access. This nowadays makes the full knowledge of its biological diversity unfeasible, mainly concerning its woody biomass and the stock and sequestration of carbon above of the soil. In this work it was defined an area of 147,5 m2 , in a typical vegetation of igapó, in Coari-AM municipal district, it was performed measurements of the branches and trunks diameters(DAP), besides of branches lengths and total height of the trees. With these values frequency branches thicknesses distribution histograms were built for four vegetable species, Bacurizeiro - Platonia insignis, João Mole - Neea cf. Mollis Spruce former J. A. Schmidt, Goiaba Araça - Eugenia Stipitata mcvaugh and Mucurão – Gustavia augusta – Membrillo.Exponents fitting with these distributions were accomplished, revealing significant results, against the hypothesis of scale exponent universality, but it evidenced a standard structural growth for the vegetation in the studied area. The species structure characterization via West's, Brown and Enquist Model enabled fractal investigation with frequencies scale factors distributions of β e γ. This analysis were in agreement with dimension fractal values obtained by means of the method of Box Counting, that showed low dimensionality. |
