Resumen
The vegetation cover of the Southwest of the State is composed by two phytophysiognomies, being a Semidecidual Seasonal Forest and Mixed Ombrophilous Forest, one of the two occurrences in different areas, these being called transition or ecotone zones. The present project is a total of data for a forest and three species of economic interest, the total and commercial volume with bark, the artificial form factor and the bark factor for a coffee fragment, located in the legal reserve on the farm of the University Tecnológica Federal do Paraná in the municipality of Dois Vizinhos in the municipality of Dois Vizinhos-PR. The two heights were adjusted in 8 hypsometric equations, based on data from 221 trees to the forest, 213 for Parapiptadenia rigida, 133 for Matayba elaeagnoides trees and 80 for Nectandra lanceolata. For the volume were adjusted 8 volumetric equations, with the data of the 47 species cubed, in order to determine a better fit. With a cubing of 47 the articular fact and the shell factor were selected. For the choice of the body and volumetric equation, we considered the statistical parameters: coefficient of determination of fit (R²aj), calculated Fischer F value (fcal) and standard error of the percentage exposure (Syx%), adopting a level of error of 5% error, as well as a graphical dispersion analysis of the residues and the height adjustment graph. It was chosen for the forest model (model 1), constructed by the equation h=0,3555+4,67261ln(d), with the result Syx% of 24; 47 and R²aj of 0,6166 the best fit model, for Parapiptadenia rigida, Matayba elaeagnoides, was model 4 (Näslund) represented by the equation h=d²/(-3,14142+1,0157d+0,03279d²) and the model 1 (Heinricksen) represented by the equation h=-3,4118+5,82764ln(d) for Nectandra lanceolata. For total and commercial volume equations, the Meyer model was identified (v=0,143130,02396d+0,0012d²+0,00304dh+0,00005867d²h-0,01953h Syx% of 19.58 and R2aj of 0.988). The artificial form factor for the total volume was 0,8042, while the artificial form factor for the commercial volume of 0,6862 and the shell factor was 0,9414.
