Abstract

En este trabajo se revisa la aplicabilidad de modelos de delimitación empírica de Áreas Metropolitanas basados en la difusión con la distancia de la concentración espacial de características socioeconómicas típicamente metropolitanas. En aras de un mayor realismo, se incorpora un factor de direccionalidad dependiente de la distancia angular a ciertas direcciones singulares a priori. Una vez estimado el modelo, la delimitación del Área metropolitana se lleva a cabo obteniendo la isopleta correspondiente a cierta fracción del valor central, como una adecuada aproximación al lugar de los puntos de máximo decrecimiento. Finalmente se ensaya el modelo para el caso del Área Metropolitana de Valencia, considerando algunas direcciones singulares alternativas y concluyéndose una delimitación que reproduce cierta disposición axial Norte-Sur. This paper examines the possibility of an empirical delimitation by means some models of metropolitan density variation with the distance. To get the most realistic view, a directional factor, depending of angular distance from some singular directions, must be embodied. Afterward model estimation, the metropolitan area is delimited as the isopleth corresponding with a particular proportion of central density, being a suitable approximation of the set of point with maximum decreasing. Finally, model is applied to the Valencian Metropolitan Area, concluding a closely (North-South) axial spatial disposition
