[en] This paper constitutes the continuation of a previous one (Blanco Gonz?lez, 2008) with which it shares objectives, study area and methodology. Both try to offer a dyachronic interpretation of the ancient human occupation of the Ambl?s Valley (?vila). This time the paper includes information from the Late Iron Age to the Middle Ages (c. 1250 AD). In particular the territorial analysis has been focused on a fundamental economic settlement issue: the access of the direct producers to the agrarian resources from the residential nuclei. With this objective, the agrarian potentiality has been measured from the grounds within the exploitation territories of a selected series of archaeological sites and modern villages. The information on the considered archaeological sites ?of presumable residential functionality? comes from extensive and intensive field surveys as much as from some excavations. The agrologic quality of the grounds whithin its surroundings has been Vigilquantified by means of the routine of a GIS which calculates the accessible land surfaces for a half-an-hour walk and an one-hour walk from each site. The findings, ordered per times, are expressed in hectares of the different agrologic classes and they appear by means of graphical summaries. The greatest discontinuity settles down in the Late Iron Age, which links the prehistoric tendency of strong imbalance on the represented land uses ?conditioned by technological locational factors or symbolic/political ones? and the historical tendency ?of clear economic orientation? characterized by a strict balance among them. The interpretation of the historic process attended ?despite its discontinuity caused by a lack of data? informs about the different rates on agrarian intensification, productive diversification and socio-political integration in the zone, reaching its algid moment at the end of the studied sequence.

[es] Este trabajo constituye la continuaci?n de otro previo (Blanco Gonz?lez, 2008) con el que comparte objetivos, ?rea de estudio y metodolog?a. Ambos pretenden ofrecer una visi?n diacr?nica de la ocupaci?n humana antigua del Valle Ambl?s (?vila), abarcando aqu? desde la Segunda Edad del Hierro hasta la plena Edad Media (mediados s. XIII d.C.). En concreto, el an?lisis territorial se ha enfocado sobre un aspecto econ?mico primordial del poblamiento: el acceso de los productores directos a los recursos agrarios desde los n?cleos residenciales. Para ello se ha cuantificado el potencial agrol?gico de los suelos dentro de los territorios de explotaci?n de una selecci?n de sitios arqueol?gicos y localidades actuales. La informaci?n sobre los yacimientos considerados ?de presumible funcionalidad habitacional? procede tanto de prospecciones sistem?ticas extensivas e intensivas, como de algunas excavaciones. La calidad agrol?gica de los suelos de su entorno se ha medido mediante la rutina de un Sistema de Informaci?n Geogr?fica que calcula las superficies de terrenos accesibles en 30 minutos y 1 hora de marcha pedestre desde los sitios. Los resultados, ordenados por ?pocas, se expresan en hect?reas de las distintas clases agrol?gicas y se presentan mediante res?menes gr?ficos. La mayor discontinuidad se establece en el Hierro II, que act?a como bisagra entre una tendencia prehist?rica de fuerte descompensaci?n en los tipos de suelos representados ?condicionada por factores de localizaci?n de tipo tecnol?gico o simb?lico/pol?ticos? y la tendencia hist?rica ?de clara orientaci?n econ?mica? caracterizada por un estricto equilibrio entre suelos. Se plantea una lectura del proceso hist?rico que, aunque discontinua ?por falta de datos?, informa de los distintos ritmos de intensificaci?n agraria, diversificaci?n productiva e integraci?n sociopol?tica en la zona, llegando a su momento ?lgido al final de la secuencia estudiada.
