| Summary: | A typology of forest stations is established for the Tolhuaca National Park, Chile. A forest station is a homogenous environmental unit, defined through its physical and biotical characteristics. In order to establish the typology of stations, three methodological stages were achieved, which are the definition of phytosociological and phytoecological groups and types of physical environments or biotopes. The identified phytosociological associations are distributed in the classes Wintero-Nothofagetea, with three associations, and Nothofagetea pumilionisantarcticae, also with three associations. The results obtained with the use of the factorial analysis of correspondences, allow establishing four phytoecological groups: mesophyllous deciduous forest, with broad-leaved evergreen species; microphyllous deciduous forest; microphyllous evergreen forest and mixed microphyllous deciduous scrub, with evergreen species. The best variables for the definition of the biotopes are altitude and relief, both factors with great influence on the local climate. The studied area is located within the temperate macroclimate and the following belts were defined: colinen, lower montane and upper montane. The proposed typology of forest stations consists of fourteen units. Se establece una tipología de estaciones forestales para el Parque Nacional Tolhuaca, Chile. El concepto de estación forestal se refiere a una unidad ambiental homogénea, definida a través del conjunto de sus caracteres físicos y bióticos. En orden a establecer la tipología de estaciones se cumplieron tres etapas metodológicas, las cuales son: la definición de grupos fitosociológicos, grupos fitoecológicos y tipos de ambiente físico o biótopos. Los grupos fitosociológicos determinados están distribuidos en la clase Wintero-Nothofagetea, con tres asociaciones, y en la clase Nothofagetea pumilionis-antarcticae, también con tres asociaciones. Los resultados obtenidos con el uso del análisis factorial de correspondencias permiten establecer cuatro grupos ... |
