Identification and prioritization criteria and indicators for Assessment Ecosystem Services are very important. In this study, we used Delphi questionnaire for identification very important criteria and indicators for Assessment of provisioning Services (Water Yield and Timber Production) and Regulating Services (Soil conservation and Carbon Storage and Sequestration) in Darabkola Watershed and Shannon Entropy technique used for calculation weight of them. Then, TOPSIS technique used for prioritization criteria and indicators of Multiple Ecosystem Services. The first, the important and effective indicators were selected and weighted by relevant experts via Delphi questionnaires. That after customization was determinate 19 indicators for Water Yield, 23 indicators for Timber Production, 25 indicators for Soil conservation and 22 indicators for Carbon Storage and Sequestration. The result of TOPSIS technique showed that the indicators of rainfall and snow persistence and the criteria of soil and climatic for water yield, the indicators of tree species type and percentage of forests and the criteria of forest resources and climatic for Timber Production, the indicators of NDVI and canopy cover percentage and the criteria of vegetation and soil for Soil conservation and the indicators of land use and NDVI and the criteria of vegetation and climatic for Carbon Storage and Sequestration in soil respectively had the highest prioritization. Also prioritization ecosystem services in Darabkola Watershed respectively had Timber Production, Carbon Storage and Sequestration, Water Yield and Soil conservation.
