IDRISI COMO HERRAMIENTA PARA LA EVALUACIÓN DE ÁREAS NATURALES PROTEGIDAS. EL CASO DEL PARQUE NACIONAL NEVADO DE TOLUCA
Abstract
Las áreas naturales en México se encuentran sujetas a intensos procesos de deterioro como resultado de la creciente intervención humana. Tal es el caso del Parque Nacional Nevado de Toluca localizado en la zona central del país. Mediante la aplicación del SIG Idrisi fue posible generar una base de datos para su caracterización general y evaluar los cambios en el uso del suelo a lo largo de un periodo de 30 años. Con los datos generados se analizaron los procesos de regeneración y deterioro de los bosques. También se determinó el nivel de adecuación del territorio para el desarrollo de
especies agrícolas y forestales dentro del área natural protegida. Los resultados obtenidos permiten corroborar que el parque nacional se viene deteriorando muy rápidamente y está siendo ocupado por actividades agrícolas y pecuarias para las que presenta niveles bajos de aptitud. La aplicación del Idrisi se vislumbra como una alternativa importante para continuar con el monitoreo del parque.
Palabras clave: SIG Idrisi, uso del suelo, Parque Nacional Nevado de Toluca, México, nivel de adecuación.
ABSTRACT
Population growth in Mexico is affecting the natural protected areas of the country. This is the case of the Nevado de Toluca National Park, located in central Mexico. Application of the GIS Idrisi has been very useful to generate a cartographical database of the protected area and to evaluate the land-use changes over a 30-year period. With the land-change results it was possible to analyze the recovery-degradation processes. In order to define alternatives for the protection of the national park, a sustainability analysis is carried out for the main forestall and agricultural species. The primary results of the application allowed us to confirm there is a serious degradation process in the protected area. The Idrisi is seen as an important alternative for continued monitoring of the park.
Keywords: GIS Idrisi, land use, Nevado de Toluca National Park, Mexico, sustainability standard.
