Mathematical modelling in volume per hectare of Pinus caribaea Morelet var. caribaea Barret y Golfari at the «Jazmines» silvicultural unit, Viñales

Abstract

Mathematical modelling constitutes a very useful tool for the planning and administration of the forest ecosystems. With the objective of predicting the behavior of volume by hectare of Pinus caribaea Moreletvar. caribaea. Barret y Golfari plantations at the «Jazmines» Silvicultural Unit, Viñales, seven non-lineal regression models were evaluated. The best goodness of fit model was the volume per hectare was the one designed by Hossfeld I, with a determining coefficient of 63, 9 % with a high significance parameter (P <0.001). The description curves for the annual mean increment with the time (IMA) and the annual periodical increment (ICA) of this variables were provided.
