| ارزشگذاری اقتصادی منابع طبیعی و الگوهای پرداخت برای بهرهمندی از آنها میتواند به کاهش تخریب محیط زیست و پیامدهای آن کمک کنند.برای براورد ارزش کاهش آلودگی رود بشار یاسوج از روش ارزشگذاری مشروط استفاده شد. برای اندازهگیری میزان تمایلبهپرداخت افراد از مدل رگرسیون لجستیک استفاده شد، و سنجههای مدلها براساس روش بیشترین راستنمایی ، برآورد شدند. تعداد 388 پرسشنامه بهروش نمونهگیری تصادفی در شهر یاسوج جمعآوری شد. نتایج نشان داد که 229 نفر از پاسخ دهندگان (حدود 60/7%) حاضر اند برای کاهش آلودگی رودخانه بشار مبلغی بپردازند. نتایج تخمین مدل لاجیت نشان داد که ضریب متغیرهای توانایی مالی، اطلاعات در پرسشنامه، جنسیت، درآمد خانوار، استفاده از رود برای تفریح و پیشنهاد در تراز 5%، و متغیر مسئولیتپذیری در تراز احتمال یکدرصد معنیدار است. متوسط تمایل به پرداخت ماهانهی هر خانواده برای کاهش آلودگی این رودخانه براساس مدل لاجیت، 61819 ریال در ماه است و ارزش ماهانهی کاهش آلودگی رودخانه بشار 2493/16 میلیون ریال برآورد شد. | ||

| Economic valuation of natural resources and patterns of payments for ecosystem services may help reduce environmental degradation and its consequences. The aim of this research was to estimate the value of decreasing environmental pollution in the Beshar River using conditional valuation method. The Logistic regression model was used to measure the willingness to pay of the individuals. The model's parameters were estimated based on the maximum likelihood method. The number of individuals who had been selected randomly in the city of yasuj and filled the questionnaires was 388. Results showed that 229 individuals (about 60.7%) were willingness to pay a fee to reduce the environmental pollution of the river. Also, the results of estimating Logit model indicated that the coefficient of variables of financial ability, being well-informed about the items in the questionnaire, gender, household income, the recreational activities in the river, and bid were significant at the 0.05 level, the responsibility variable was significant at the 0.01 level. The willingness to pay of each household for reducing the environmental pollution of the river according to the Logit model was 61819 Rls per month, and the monthly value of the pollution reduction in the Beshar River was estimated at 2493.16 million Rls. | ||
