One of the cultural characteristics of eastern zone at central part of Zagros Range during 3rd millennium BC and at early Bronze Age is the extension of the related habitats to Yaniq Culture (Ancient City near Abhar) in this region. Within field study conducted in 2008 in the plains covering central Zagros eastern side that is situated in Alvan Basin, we managed to identify more than habitats relating to Early Bronze Age. According to analysis done on the data derived from this survey in GIS software environment and by adaption of statistical methods, the relationship between site of habitat and its ecological factors has been assessed. Based on design of this model, we managed to interpret some reason for creation of settlements in this region during Early Bronze Age as well as the existing relationship among the given habitats and archaic routes passed between Iranian Plateau and Mesopotamia at 3rd millienium BC. Using GIS software made it possible for us to identify the reason for many settlement displacements based on archeological evidences at Early Bronze Age so that to describe their settlement models. We can purpose this point, as result of this study, that one may suggest a type of pseudo- nomadic and dry- farming system as economic system for people at Early Broze Age within a limited scale in this region.
