Productividad de las plantaciones de pino ponderosa (Pinus ponderosa Dougl. ex Laws.) de la Comuna de Coyhique, Provincia de Coyhaique, XI Región / Productividad de las plantaciones de pino ponderosa (Pinus ponderosa Dougl. ex Laws.) de la comuna de Coyhaique, provincia de Coyhaique, XI RegiónParra Jaque, Carlos Alfonso January 2009 (has links)
Memoria para optar al Título Profesional de Ingeniero Forestal / Ecuaciones altura-diámetro, de volumen, determinación de calidad de sitio y elaboración de
modelos de productividad son testeados para plantaciones de pino ponderosa (Pinus
ponderosa Dougl. ex Laws.) no raleadas de la comuna de Coyhaique, provincia de
Coyhaique, región de Aysén.
Los datos para los ajustes se obtienen de 91 parcelas instaladas en todo el rango de edades,
número de árboles por hectárea y distribución geográfica de las plantaciones de pino
ponderosa.
Seis ecuaciones H-D (dos lineales y cuatro no lineales) de las más ampliamente usadas en
pino ponderosa, son ajustadas con un set de 1.378 datos H-D obtenidas de las 91 parcelas
antes indicadas. Los modelos son ajustados para cada una de las 91 parcelas y comparados
según error estándar de estimación. El siguiente modelo no lineal es el escogido porque
convergió más eficientemente respecto a los otros modelos no lineales y tiene más
flexibilidad que las funciones lineales, además tiene un bajo error estándar de estimación.
