چکیده مقاله :

زمینه و هدف: تعیین ارزش های غیر بازاری، برای حفاظت کالاهای زیست محیطی مانند زیست گاه ها و چشم اندازها اهمیت فراوانی دارد. هدف از تحقیق حاضر ارزش گذاری حفاظتی منطقه حفاظت شده خاییز با استفاده از روش ارزش گذاری مشروط می باشد.روش بررسی: در این تحقیق برای بررسی تأثیر متغیرهای توضیحی مختلف بر میزان تمایل به پرداخت پاسخ گویان جهت ارزش حفاظتی از مدل رگرسیونی لوجیت استفاده شد. داده های مورد نیاز از طریق تکمیل 196 پرسش نامه جمع آوری گردید.یافته ها: نتایج نشان داد 71 درصد پاسخ گویان تمایل خود را برای مشارکت در حفاظت از منطقه اعلام کردند. نتایج تخمین مدل لاجیت نشان داد، ضریب متغیرهای گرایش های زیست محیطی، مسوولیت پذیری، توانایی مالی، عضویت در سازمان محیط زیستی و پیشنهاد معنی دار شده است. نتایج مشخص کرد مقدار مورد انتظار تمایل به پرداخت برابر 28/18861 ریال می باشد. ارزش حفاظتی سالانه منطقه مورد مطالعه نیز برابر 7/287382 میلیون ریال تعیین شد. از تقسیم این رقم بر کل مساحت بوم سازگان منطقه مورد مطالعه، ارزش حفاظتی سالانه هر هکتار از این بوم سازگان برابر 8888 هزار ریال (با توجه به مساحت 32332 هکتار منطقه) به دست می آید. پیشنهاد می شود دست کم سالانه معادل 8888 هزار ( ارزش حفاظتی سالانه هر هکتار) ریال برای حفاظت از منطقه خاییز سرمایه گذاری شود. بوم سازگان منطقه مورد مطالعه ارزش های فراوان دیگری ( حفظ آب و خاک، گیاهان دارویی و محصولات فرعی، جذب و ذخیره دی اکسید کربن و تولید اکسیژن، تنوع بیولوژیکیو ... ) هم دارد که ارزش آن ها باید برآورد شود.بحث و نتیجه گیری: انجام این مطالعه در شرایط حاضر گام مهمی به منظور حفاظت مناطق حفاظت شده و منابع طبیعی و حرکت در راستای توسعه پایدار است. از طرفی برای برنامه ریزان، مسوولین و سیاست گزاران توجیهی فراهم می کند تا کمیت و کیفیت منابع طبیعی را حمایت بکنند.

چکیده انگلیسی:

Background and Objectives: The value of non-market for environmental goods such as habitat protection and perspectives are important. The aim of this study was to evaluate the protective Khaeiz protected area is by use of contingent valuation method.Method: In this study the effect of different explanatory variables on respondents' willingness to pay for the Protection of logit regression model was used. The required data from 196 completed questionnaires were collected.  Findings: 71% of respondents expressed a willingness to contribute to the protection of the region. Results of logit model estimation showed that the index trend of environmental variables, accountability, financial, environmental and offered membership in the organization are significant. The results showed that the expected value of the willingness to pay was 23948/5 million Rials. The monthly value of protecting the region against 18861/28 million rials respectively. The protective value against was determined 287382/7million rials annually in the study area. Dividing this figure by the total area of ​​ecosystems studied, the average per hectare of ecosystem protection against 8888 thousand (according to the area of ​​32332 hectares’ area) is obtained. It is recommended at least annually, equivalent to 8888 million (annual preservation value per hectare) Rials for investment protection Khaeiz area. It represents the estimated total value of ecosystem protection in the region. In other words, the ecosystem of the region also has many other values ​​for example, biological control of pests, pollination, water and soil conservation, medicinal plants and byproducts, capture and storage of carbon dioxide and produce oxygen, biological diversity , prevent soil erosion, combat air pollution, noise reduction, mitigation and climate stylized, green spaces and landscape and natural scenery, temperature adjustment, increase groundwater resources and consequently the springs and rivers, others noted that their value should be estimated.  Discussion and Conclusion: In this study, the current situation is an important step to safeguard protected areas and natural resources and move towards sustainable development. Also for planners, managers and decision-makers provide justification to the quantity and quality of natural resources to support them.
