Application of hyperbolic function curves in construction site index

Abstract

This study evaluated the efficiency of the hyperbolic function for construction of anamorphic and polymorphic site index curves. The site index curves were constructed using the methods: guide-curve, difference equation, parameter prediction, Hammer and site index preliminarily defined. To apply these methods data from permanent plots in stands of eucalyptus were used. The efficiency was confirmed, being the function indicated to describe anamorphic and polymorphic trends that can be used in the classification of productivity capacity of eucalypt stands.
