Equacoes de volume para uma floresta secundaria no planalto do Tapajos Belterra, PA.
Single and two parameter volume equations were developed for a secondary forest located in the Tapajos plateau-Belterra, Para. Sixty sample-trees of several species were measured to produce general equation and sixty Vochysia maxima trees were measured to obtain equations for this particular species. The sample trees were measured according to an uniforme distribution. Eleven models found in the literature and two equations obtained by stepwise regression were compared. The tables of the relative residuals [(Y
