El área registra cambios en la cobertura del suelo, intensa división predial y degradación de los sistemas naturales. La metodología comprendió (1) análisis cartográfico, matriz de confusión e índice de kappa y (2) análisis/cuantificación de cambios mediante matriz de cambio. Los resultados permitieron identificar áreas sometidas a mayor presión de uso, identificándose las categorías "cultivos-praderas naturales" y "plantaciones forestales" como las coberturas que concentran el 79,5% de la superficie total del cambio neto en el área, con tasa de ganancia de superficie de uso forestal con especies exóticas de 432 ha año-1 en desmedro de suelos de uso agropecuario. Nuestros resultados reafirman la necesidad de analizar la evolución en el uso del suelo previo a la identificación de las potencialidades del recurso suelo para soportar nuevas actividades productivas.
The results confirmed the reduction in the areas of agriculture and livestock and the increase of exotic plantations use on surfaces intended for agricultural use. The significant transitions were the conversion at a rate gain of 384 ha/year of "Farmlands" to "Exotic plantations", the abandonment at a loss rate of 119 ha/year of "Perennial grasslands" to "Native vegetation", the degradation at a loss rate of 93 ha/year of "Native vegetation" to "Perennial grassland", and the revegetation at a rate gain of 60 ha/year of "Exotic plantations" to "Native vegetation". The new patterns and trends in the use and intensity of land use reaffirmed the need for studies on the updated status of natural resources, particularly soil resources. This work, we believe, is a technical tool to support the sustainable management of a territory and the decision-making processes on land use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
