Abstract :
The impact of environmental factors on archaeological sites, depends on their geographic conditions. In this study, two cities (Darreh Shahr and Abdanan of Ilam province) were considered as geographical scope and impact of environmental factors on the destruction of archaeological sites were studied. In this research, GIS software was used for overlaying environmental factors and also TOPSIS model was used for ranking impact factors on archaeological sites. Ten environmental factors such as height, aspect, slope, rainfall, temperature, erosion class, distance from river and fault, land use and geological formations were selected as affecting factors on these sites. Results shows that rainfall, aspect and geological formations are more effective on destruction of archaeological sites. Also impact of these factors on the archaeological sites of the cities seems equal.
