سابقه و هدف: جنگلها علاوه بر تولید چوب، سودمندیهای زیست محیطی و اجتماعی اقتصادی زیادی به همراه دارند که اغلب آنها بدون بازار هستند.
مواد و روش ها: در این پژوهش پنج مورد از خدمات جنگل از منظر اقتصادی مورد توجه قرار گرفت و ارزشگذاری شد. به این منظور ارزش کارکرد تفرجی با بکارگیری روش ارزشگذاری مشروط و ارزش ترسیب کربن، ارزش نگهداشت عناصر غذایی خاک، ارزش تنظیم آب جاری و ارزش محصولات غیرچوبی منطقه با بکارگیری روش هزینه جایگزین برآورد شدند، سپس ارزش کل اقتصادی این کارکردها برآورد شد.
یافته ها: نتایج نشان داد که مجموع ارزش اقتصادی اکوسیستم جنگلی در سال معادل 1/576413505 هزار تومان و ارزش اقتصادی هر هکتار از آن معادل 560/17243407 تومان در هکتار است. همچنین ارزش کارکرد ترسیب کربن با رقمی معادل 1/574114967 هزار تومان درسال بیشترین سهم را از ارزش اقتصادی کل جنگل نوژیان به خود اختصاص داد و کارکرد تفرجی کمترین ارزش را بین کارکردها به خود اختصاص داد که معادل 126618هزار تومان در سال است.
نتیجه گیری: این نتایج بیانگر آن است که ارزش اکولوژیکی جنگل نوژیان بیشتر از جنبههای اقتصادی و اجتماعی آن است. همچنین از نتایج مطالعه انجام شده چنین میتوان نتیجه‌گیری کرد که سرمایههای طبیعی با توجه به روند بهره‌برداری درآینده بیشتر تحت فشار قرار میگیرند و کمیابتر میشوند، لذا ضرورت دارد که با استفاده بهینه و مناسب از این اکوسیستمهای ارزشمند به حفاظت از این میراث طبیعی کمک نمود. با دانستن ارزش اقتصادی کل اکوسیستمها، برنامهریزان و سیاستگزاران قادر به تصمیمگیری جامعنگرتر و تعیین اولویت بین گزینههای موجود خواهند بود که خود باعث استفاده بهینه میشود.
