Modelo generalizado no-lineal altura-diámetro con efectos mixtos para siete especies de Pinus en Durango, México

Abstract

Durango es el principal estado en México para la producción de madera (28.5 % del total nacional). Se estima que la superficie bajo aprovechamiento es de 2 millones de hectáreas; razón por la cual, la ordenación forestal es una tarea importante para los manejadores silvícolas. El conocimiento sobre la relación altura-diámetro (h-d) de los árboles se utiliza, principalmente, para caracterizar la estructura del rodal, estimar el volumen de los árboles individuales o del rodal, y para determinar la altura dominante con el propósito de evaluar la productividad vía el índice de sitio. En este trabajo se desarrolló una ecuación generalizada para describir la relación h-d de siete especies de coníferas en los bosques mezclados del noroeste de Durango, México. La ecuación considera como variables independientes al diámetro normal, altura dominante, área basal y la densidad. Para la variabilidad entre 44 sitios permanentes, el ajuste de la mejor ecuación fue mediante el enfoque de modelos mixtos no lineales. El modelo generalizado desarrollado explicó 82 % de la variabilidad total de los datos observados. Para calibrar el modelo mixto se determinó que se requiere medir la altura total de una submuestra de tres árboles de clase diamétrica promedio dentro de cada parcela. La ecuación generada constituye una herramienta para el manejo forestal de los bosques mezclados del área de estudio.
