Resumen
El objetivo de este estudio es analizar el cambio de uso del suelo que ha experimentado la zona minera del cantón Portovelo desde el año 2001 hasta el año 2016, para generar insumos de información que permitan mejorar la planificación urbana, ambiental y territorial. Para este proceso se utilizaron imágenes Landsat del mes de junio para los años de análisis. La clasificación de las imágenes de satélite se realizó mediante el método supervisado de Máxima Probabilidad la misma que permitió obtener nueve categorías. Los resultados fueron aceptables con un coeficiente kappa de 0.908, los mismos que indicaron la existencia de un cambio significativo sobre todo en la categoría de cuerpos de agua artificiales con una tasa de cambio de 1200,50% de incremento seguida de la categoría infraestructura antrópica con una tasa de cambio de 393,59% debido a la actividad minera y por ende a la implantación de nuevas plantas de beneficios para procesamiento de minerales metálicos.
The objective is to analyze the change in land use that has been experienced the mining area of the Portovelo city from 2001 to 2016, to generate informational inputs to improve urban planning, environmental and territorial planning. For this process, Landsat images were used for the analysis years of the same station. The classification of the satellite images was done by means of the supervised method of Maximum Probability the same one that allowed to obtain nine categories. The results were acceptable with a kappa coefficient of 0.908, which indicated the existence of a significant change especially in the category of artificial water bodies with a rate of change of 1200.50% increase followed by the category anthropic infrastructure with an exchange rate of 393.59% due to the mining activity and therefore to the implementation of new profit plants for the processing of metallic minerals.
