Análisis de la eficiencia del uso de los diámetros dominantes en la construcción de curvas de índice local con cinco métodos analíticosAnalysis of the efficiency of the use of dominant construction in diameter curve with five local index analytical methods RESUMENEl objetivo de investigación fue analizar el uso del diámetro dominante a la altura del pecho (Dapd) para la construcción de curvas de índice local. Para ellos se evaluó comparó cinco métodos analíticos (Curva guía, Ecuación de diferencias, modelo linear de Schumacher y Hall, Índices de local definidos preliminarmente, de Hammer y Predicción de parámetros) con la variable Dapd, dando mejor resultado el método de Índices de Local definidos preliminarmente con un 23% de variación en la clasificación de parcelas en función a la clasificación con la altura dominante. Este método fue ajustado con el modelo de Richards y se obtuvo un coeficiente de correlación entre los datos observados y los estimados de 0,982.Palabras clave: calidad de sitio, DAP, índice local. ABSTRACTThe objective ofthis research was to analyze the use ofthe dominant diameter at the breast height (Dbh) for the construction oflocal index curves. For them it was evaluated comparing five analytical methods (Guiding Curve, Differential Equation, Schumacher and Hall linear model, Preliminary Defined Local Indexes, Hammer and Prediction of parameters) with the variable Dbh, giving better result the Local Indices method defined preliminarily with a 23% variation in the classification ofplots as a function ofthe classification with the dominant height. This method was adjusted with the Richards model anda correlation coefficient between the observed data and the estimated values of0.982 was obtained.
