| description | Despite its importance in ecology, forestry and resource management the relationship between remote sensing data and forest inventory data are still poorly understood, in particular regarding the structural complexity of woody canopy elements. In this paper we evaluate by multivariate techniques and Generalized Linear Models (GLM), the influence of 4 woody canopy structure variables by strata (height, DBH, crown diameter and density) on the Landsat TM reflectance data. We analyzed three forest types in the Cofre de Perote National Park. Biplots suggest differences related to the type of forest and the metric expression of structural attributes. GLM indicate that the total reflectance shows differential response that can be associated to canopy structural complexity and the type of forest with some limitations related to the sensitivity of the sensors. Landsat bands 1-3, 5-7 showed a better association with forest complexity variables, in particular for Pinus hartwegii forest and mixed forest. Apparently forest structural attributes and limitations of Landsat sensor sensitivity itself prevents the identification of reliable association between reflectance and complexity variables in Abies religiosa forest. |

La relación entre datos de instrumentos de percepción remota y datos de inventario de bosque, en particular de la complejidad estructural de los elementos leñosos del dosel es un asunto pobremente entendido no obstante su importancia en ecología, silvicultura y manejo de recursos. En el presente trabajo se evaluó por medio de técnicas multivariadas (biplot) y Modelos Lineales Generalizados (MLG), la influencia de los diferentes estratos leñosos del dosel de cuatro variables de estructura (altura, DAP, diámetro de copa y densidad de individuos) sobre la reflectancia de datos Landsat TM en tres tipos de bosque en el Parque Nacional Cofre de Perote. Los resultados biplot indican diferencias relacionadas con el tipo de bosque y la expresión métrica de los atributos estructurales. MLG indican que la reflectancia total es dependiente de la complejidad estructural del dosel, del tipo de bosque con ciertas limitaciones derivadas de la sensitividad de los sensores. Las bandas Landsat 1-3, 5-7 mostraron una más clara relación con atributos de la complejidad forestal, en particular para bosque de Pinus hartwegii y bosque mixto, al parecer las dimensiones estructurales del bosque y limitaciones en la sensitividad de los sensores Landsat impiden explicar la reflectancia a partir de la complejidad en el bosque de A. religiosa.
