Abstract
Background and Objective: Human societies have long enabled settlements by creating habitable environments that are suitable for their surroundings. In archaeology, this approach emphasizes the significant role of environmental factors in evaluating settlements within each period. Besides identifying the extent of environmental impacts, this perspective reveals the degree of adaptation of habitats to prevailing environmental conditions. As spatial tools have advanced, GIS archaeology has evolved, allowing the visualisation of ancient settlements and the analysis of changes in spatial use over time.
Methodology: This study uses environmental factor analysis to examine the settlement and distribution patterns of 161 ancient sites in the Qezel Ozan Basin with a GIS information system. After the analysis of GIS maps, it assesses and distributes these settlements in relation to the natural environment, focusing on water resources, altitude, slope, and land use.
Results and Findings: Since the 1st millennium BCE, the foothills and plains have seen an expansion in the dispersion of communities. 2. The 1st millennium BCE villages are mostly found at elevations of -2000 m, with an average slope of 5-10. They are situated less than -500 m from rivers, and the choice of land type has been made. A decrease in population and the type of seasonal deployments is indicated by altitude, steep slopes on riverbanks (plains to foothills). 3. Land use: The distribution of ancient sites in the Qezel Ozan river basin is indicated by the rise and development of agriculture, transportation routes along water resources, trade exchanges, and regional and interregional links.The evolution of settlements in the East Kurdistan region from the Chalcolithic to the Islamic era demonstrates the adaptation and competition of inhabitants with the natural environment in the Qezel Ozen basin. It also provides insights into the complex social development of the region.
