Modelización de territorios ganaderos en la alta montaña al final del Neolítico: una integración de análisis espacial e información etnográfica

Recent archaeological research in the mountains of Ibe­ria is beginning to document extensive sequences of occu­pation during de Holocene. In the Pyrenees stands out the location of a considerable number of sites date to 3350 and 2350 cal BC (Late Neolithic / Chalcolithic). This phenome­non seems to link with the consolidation of the livestock exploitation in the alpine and subalpine zones. This work undertakes a the dispersion pattern analysis of archaeolog­ical sites of this period in the National Park of Aiguestortes i Estany de Sant Maurici, in the Central Pyrenees. Using GIS it defines influence areas around the sites and the opti­mal paths between them so as to evaluate two important variables in any livestock practice: the accessibility to the settlements and grazing areas. For comparative purposes the dispersion pattern of modern and contemporary sites is analysed as well. This study allows to conclude significant differences in the distribution of the sites both ancient and recent in relation to pastures and roads.
