چکیده مقاله :
In this study, the recreational value of ShirinSou Wetland of the Kabodarahang County in Hamadan Province, Iran was estimated and the visitors' willingness to Pay (WTP) was measured by using Contingent Valuation Method (CVM) and One and One Half Bound model (OOHB) dichotomous choice (DC) questionnaire. The results show that 81 percent of investigating individuals will pay for recreational usage of the studied wetland. Estimated WTP is 44671 IRR (US$ 1.68) for each visitor. The total annual recreational value of this wetland is estimated at about 809 (million IRR) (or US$ 30348). Furthermore, the variables of proposed bids and visitors' monthly income are statistically significant at 1%; so, these two variables are considered as the most important factors affecting visitors' WTP. Also, these tow variables have negative and positive effect on WTP, respectively. Age and level of education were the next effective factors with significant impact at the 10% level. Policy makers can take these values into consideration in the decision-making process of the development of the wetlands.
در این مطالعه، ارزش تفریحی تالاب شیرین‌سو در شهرستان کبودرآهنگ استان همدان بر اساس تمایل به پرداخت با استفاده از روش ارزشگذاری مشروط و پرسشنامه الگوی یک و نیم بعدی صورت گرفته است. تمایل به پرداخت با استفاده از الگوی لاجیت اندازه‌گیری شده است که ضرایبش بر اساس روش حداکثر درستنمایی برآورد شده است. نتایج نشان می‌دهد که 81 درصد از افراد مورد بررسی حاضرند مقداری را برای استفاده تفریحی از این تالاب بدهند. متوسط تمایل به پرداخت 44671 ریال (68/1 دلار) برای هر بازدیدکننده است. ارزش تفریحی سالانه این تالاب در حدود 809 میلیون ریال (30348 دلار) برآورده شده است. متغیر مقدار پیشنهاد و درآمد بازدیدکننده از نظر آماری در سطح 1 درصد معنی‌دار بوده و به ترتیب دارای اثرات منفی و مثبت بر تمایل به پرداخت بوده‌اند. این دو متغیر به عنوان مهم‌ترین عوامل اثرگذار بر تمایل به پرداخت بازدیدکننده شناخته شده است. سن و سطح تحصیلات از دیگر عوامل اثرگذار بوده که در سطح 10 درصد معنی‌دار بوده‌اند. یافته‌های این تحقیق می‌تواند مد نظر سیاستگذاران و مدیران در بخش محیط زیست به منظور سرمایه گذاری جهت توسعه و بهبود وضعیت تالاب قرار گیرد.
