Regional input- output table of Ilam province was used to investigate the manner of spatial effect of dust storm in the studied region. Days associated with the dust phenomenon were identified as sample (control) days during the existing statistical period for six selected station based on the number of days that province has faced dust storm and with the closure of various economic and social sectors has led to a decrease in the production level of the province. The extent of its negative effect on province’s income was calculated.

By use of valid identifying keys such as Navid pour (2008), samples recognizes, frequency of scorpion species in each climate region has showed and their distribution map by use of GIS software has drawn. In Ilam province, among 390 hunted scorpion, 10 species include Hottentotta saulcyi (23.07), Mesobuthus eupeus (22.56), Compsobuthus matthiesseni (13.07), hemiscorpius lepturus (12.3), Orthochirus iranus (7.94), Razianus zarudnyi (4.87), Androctonus crassicaudata (4.1), Buthacus macrocentrus (3.33), Scorpio maurus (2.56), Odontobuthus bidentatus (1.02) scorpion identified.
