FUNCIÓN DE AHUSAMIENTO Y VOLUMEN COMPATIBLE PARA Pinus arizonica Engelm. EN EL SUROESTE DE CHIHUAHUA
Keywords:
Taper, volumetric estimations, Biging model, Pinus arizonica Engelm., commercial volume, compatible volumeAbstract
Pinus arizonica. is one of the most abundant and regularly used species that grows at the southeastern part of Chihuahua state, and covers 80 per cent of the forest territory, with an annual wood production near 160,000 m2; however, knowledge about the estimation of its commercial volume is limited. Thus, the aim of this study was to know its taper and to formulate a compatible equation that guarantees their operation application. Six models including linear and non-linear equations were tested and tted to 2,230 data pairs from 319 felled trees from harvesting operations. Fitting goodness was examined through the comparison of the adjusted coef cient of determination, root mean square error and a precision index. Statistical techniques to verify and correct problems of collinearity, autocorrelation and heteroscedasticity were included. Biging model had the best predictionability;itsmathematicalintegrationmakesitpossibletogetataperexpression compatible to total and commercial volumes for trees. This equation is recommended to assess diameter and height of the stem and total and commercial volume for the species that was analyzed.
