GEOGRAFIA117862020-02-04T21:56:56Z Fragmentation and connectivity of the natural cover at county level in Costa Rica, during 2000 and 2015 years Fragmentación y conectividad de la cobertura natural a nivel cantonal en Costa Rica durante los años 2000 y 2015 Morera_Beita, Carlos Sandoval-Murillo, Luis nature cover, land use, fragmentation, connectivity, biometric index. cobertura natural, uso de la tierra, fragmentación, conectividad, índice biométrico This research proposes the formulation of a fragmentation / connectivity index that assesses the condition of natural cover at the canton level for Costa Rica based on spatial distribution considering the variables: area of the county, the natural coverage area, the number of fragments and distance of neighborhood between the fragments of the natural cover, for the years 2000 and 2015. The images Landsat 7 for the year 2000 and Landsat 8 for the year 2015 were used where the land use categories for each year were derived through supervised classification with ERDAS software and with ArcMap10.5 biometric indices were estimated using the Vargas equation (2008) which was modified for its application. Within the results, we identified the cantons that present greater or lesser fragmentation and connectivity of their natural coverage during the study period. En esta investigación se plantea la formulación de un índice de fragmentación/conectividad que valora la condición de las coberturas naturales a nivel de cantones para Costa Rica, basado en la distribución espacial, considerando las variables: superficie del cantón, la superficie de cobertura natural, el número de fragmentos y distancia de vecindad entre los fragmentos de la cobertura natural, para los años 2000 y 2015. Se utilizaron las imágenes Landsat 7 para el año 2000 y Landsat 8 para el año 2015, donde se derivaron las categorías de uso de la tierra para cada año mediante clasificación supervisada con el software ERDAS y con el ArcMap10.5, se estimaron los índices biométricos usando la ecuación de Vargas (2008), la cual para su aplicación fue modificada. Dentro de los resultados se identificó los cantones que presentan mayor o menor fragmentación y conectividad de su cobertura natural durante el periodo de estudio.
