DETECCIÓN DE CAMBIOS RECIENTES EN LA COSTA VASCA MEDIANTE ORTOFOTOGRAFÍA

摘要: The continuous degradation of natural habitats is specially severe in the coastal fringe, as a consequence urbanization and increase demographic pressure. objective this contribution to analyse recent changes coast Basque Country (northern Spain) through comparison ortophotography years 2002 2004, at 0.25 m spatial resolution. Habitat identification, following EUNIS classification from European Environmental Agency, comprises supralittoral intertidal zones, infralittoral zone (until 5 metres water depth), including also estuaries saltmarshes. main during period are 32,3 ha artificial claimed sea, increasing 18,9 grey dunes dry beaches 9,9 Conversely, loss 24,8 sand 31,6 transitional waters, was detected. These caused mainly by harbour construction saltmarsh dune system regeneration programmes. results obtained here show rapid artificialization land narrow fragile fringe littoral.
