Abstract

The objective of this study was to evaluate the efficiency of the function log-Pearson type V to describe the diametric structure of even-aged stands of eucalyptus and propose a model using this function. The modeling performed by the function log-Pearson type V was compared with the modeling performed with the Weibull function and hyperbolic. It was used data from permanent plots of eucalyptus stands located in the Midwest region of Minas Gerais State, Brazil. The function of Pearson type V was tested in three different configurations, with three and two parameters, and with the parameter replaced by the minimum diameter location of the plot. Adherence functions of the data were confirmed by applying the Kolmogorov-Sminorv (KS). All adjustments to the data presented adherence by KS test. The Weibull and hyperbolic functions presented better function performance than that observed applying Pearson type V.
