چکیده

تالاب سدّ آبشینه، به علّت موقعیّت خاص آن در تأمین آب شرب مردم همدان و قرار گرفتن در مسیر مهاجرت پرندگان مهاجر، از نظر زیست‏محیطی حائز اهمیت است. با توجه به ارائه کالاها و خدمات متعدد و ارزشمند توسط این تالاب، هدف از انجام مطالعه حاضر تعیین ارزش حفاظتی تالاب آبشینه و اندازه‌گیری میزان تمایل به پرداخت ساکنان شهر همدان برای حفاظت از آن بود. بدین منظور، از روش ارزش‏گذاری مشروط در یک بازار فرضی بر مبنای رجحان عمومی استفاده شد. همچنین، برای برآورد مدل، از الگوی لاجیت و روش برآورد حداکثر درست‏نمایی و برای استخراج مبالغ پیشنهادی، از روش انتخاب دوگانه دوبعدی استفاده شد. نمونه‌گیری با استفاده از روش نمونه‌گیری تصادفی خوشه‌ای صورت پذیرفت و داده‌های مطالعه از طریق مصاحبه با 209 نفر از سرپرستان خانوار شهر همدان در سال 1397 جمع‌آوری شد. نتایج تحقیق نشان داد که متغیرهای سطح تحصیلات، درآمد خانوار، میزان آشنایی با تالاب و آگاهی در خصوص خدمات زیستگاهی تالاب اثر مثبت و متغیر مبلغ پیشنهادی اثر منفی بر میزان تمایل به پرداخت افراد برای حفظ تالاب آبشینه دارند. میزان متوسط تمایل به پرداخت برای حفظ تالاب حدود 2787 تومان و ارزش حفاظتی سالانة تالاب بیش از 83/3 میلیارد تومان برآورد شد.

چکیده [English]

Due to its special position in providing drinking water for the people of Hamadan province of Iran and being on the migration path of migratory birds, Abshineh Dam Wetland is important from an environmental point of view. Considering the provision of numerous and valuable goods and services by this wetland, this study aimed at determining the protection value of Abshineh Wetland and measuring the Hamadan residents' willingness to pay for its protection. For this purpose, conditional valuation method was used in a hypothetical market based on general preference. Also, to estimate the model, the logit model and the maximum likelihood estimation method were used, and the two-dimensional double selection method was used to extract the suggested amounts. Sampling was done using cluster random sampling method and study data was collected through interviews with 209 heads of households in Hamadan city in 2018. The study results showed that the variables of education level, household income, the level of familiarity with the wetland and knowledge about the habitat services of the wetland had positive effects, and the proposed amount variable had a negative effect on the willingness of people to pay for the preservation of the Absheena wetland. The average amount of willingness to pay for the preservation of the wetland was about 27870 IRI Rials and the annual protection value of the wetland was estimated to be more than 38.3 billion IRI Rials.
