مقدمه: به علت محدودیت منابع آبی در کشور، تعیین ارزش اقتصادی آب به عنوان رویکردی جدید، در مدیریت و بهره­برداری از منابع آب ضروری به شمار می­آید. بر این اساس هدف کلی این پژوهش برآورد ارزش اقتصادی آب در باغات شهرستان گچساران می‌باشد. روش: جامعه آماری در پژوهش حاضر شامل باغداران شهرستان گچساران است که تعداد آنان 2900 نفر بود. برای انتخاب نمونه آماری از جدول کرجسی و مورگان استفاده شد و بر اساس این جدول تعداد افراد نمونه ۲۶۲ نفر تعیین شد. ابزار گردآوری داده ها پرسشنامه محقق ساخته بود که برای سنجش روایی آن از پانل متخصصان و برای محاسبه پایایی ابزار گردآوری تحقیق از آزمون آلفای کرنباخ استفاده گردید. مقدار آلفای کرونباخ کل پرسشنامه78/0 بدست آمد که این مقدار برای انجام تحقیق قابل قبول می­باشد. نتایج: با توجه به مجموع کشش­های تولیدی نهاده­های تابع کاب-داگلاس میزان بازده نسبت به مقیاس محصولات باغی در شهرستان گچساران در سال 1396، 7.55 می­باشد که نشان می­دهد با افزایش 7.55 درصدی نهاده­های تولید در شهرستان گچساران، عملکرد محصولات باغی 7.55 درصد افزایش می­یابد. به منظور تعیین ارزش اقتصادی آب کشاورزی، از توابع تولیـد کاب داگلاس، ترانسندنتال و ترانسلوگ استفاده شده است. نتیجه گیری: نتایج حاصل از برآورد توابع تولید مورد بررسی نشان داد تابع کاب داگلاس با توجه به سادگی و ضرایب معنی­دار نسبت به سایر توابع (ترنسندنتال و ترانسلوگ) برتری داشت و برآورد ارزش اقتصادی آب بر اساس آن برابر با 585،060 ریال می­باشد
