Resumen

El patrón espacial de los indicadores seleccionados de sellado del suelo se ha explorado en la provincia de Barcelona como una contribución al debate sobre el consumo de suelo impulsado por la urbanización en la Europa mediterránea. Mediante el uso de técnicas de exploración multidimensional y de análisis espacial, se han obtenido indicadores de sellado del suelo (porcentaje de suelo permeable, terrenos impermeables per cápita, intensidad de sellado del suelo y diversidad en la intensidad del sellado del suelo) a partir de un mapa del suelo urbano sellado en la escala municipal. Todos los indicadores se correlacionaron con la distancia desde el centro de Barcelona. Los resultados sugieren que el patrón de sellado del suelo en Barcelona refleja las distintas fases de urbanización observadas después de la Segunda Guerra Mundial e indican la rápida transición de una forma urbana monocéntrica y compacta observada en la década de los años cincuenta del siglo pasado a una aglomeración más dispersa. El artículo trata sobre el uso de indicadores de impermeabilidad para la evaluación de los cambios de uso del suelo en las grandes regiones urbanas mediterráneas.
