| چکیده | ||
| کارکردهای یک منبع طبیعی از جمله اکوسیستم مرتع به چهار گروه کارکردهای تنظیمی، زیستگاهی، تولیدی و اطلاعاتی قابل تقسیم میباشند که در پژوهش حاضر، ارزش اقتصادی چمنزارهای ترگور ارومیه از منظر تولید علوفه و بهرهبرداری از ثعلب بهعنوان کارکرد تولیدی، مورد بررسی قرار گرفت. برای این منظور، از بین مناطق پراکنش ثعلب، شش مکان به مساحت 120 هکتار که نمایندۀ سطح وسیعی از چمنزارهای منطقه میباشند، انتخاب گردید. سپس در تودۀ معرف هر یک از آنها، تولید علوفه و مقدار تولید غدۀ ثعلب، اندازهگیری و ارزش ناخالص آنها بهروش بازاری محاسبه گردید. بر مبنای نتایج حاصل، هر هکتار از چمنزارهای منطقه، بهطور متوسط قادر به تولید 78/1731کیلوگرم علوفه و 02/4 کیلوگرم غده ثعلب بهعنوان محصول فرعی در یک فصل رویش میباشند که ارزش ناخالص هر هکتار از آنها از منظر کارکرد تولید علوفه و بهرهبرداری از ثعلب، بهترتیب 88/16 و 72/44 میلیون ریال میباشد. از نتایج پژوهش حاضر میتوان در تعیین خسارت ملی وارده به عرصههای مرتعی و محاسبۀ حساب‌های ملی سبز، استفاده کرد. | ||

| Functions of a natural resource, including rangeland ecosystems, can be divided into four groups of regulatory, habitat, production and information functions. Therefore, in this study, the economic valuation of forage production function and utilization of rhizome orchid were in terms of performance and utilization of orchid feed, studied in Trgvr grasslands of Urmia. For this purpose among, the distribution areas of orchids in the grasslands area, six locations with a total area of 120 hectares with different water levels that are representative of a wide range of grassland area, were selected. Then, The production of different vegetation forms and the amount of orchids production was measured in represetive sample, and the economic value was estimated by marketing method according to the results each hectare of grassland area is able to produce 1731.78 kg forage and 4.02 kg orchids in a growing season, whit it's economic value of each hectare of forage production and utilization of orchids in terms of function, respectively equal to 16.88 and 44.72 IRR. The results of the study are useful in determine the acceptable level of damages grassland area and to calculated and green national accounts. | ||
