Semi-arid ecosystems provide many direct and indirect services and contribute substantially to the gross national production (GNP) of country. Valuation of these ecosystems is necessary for better conservation and exploitation management. In this investigation, ecological values of 608 ha of Palangdarreh region in South West of Qom province were studied. Seventeen kinds of ecosystem services and functions were identified. Each service or function was valuated using appropriate methodology. Total value for all services and functions was estimated as much as 4,400,000 Rials ($550) per rhectare per annual.
