鹞落坪自然保护区非使用价值的评估

Assessment of non-use value of the Yaoluoping national nature reserve

选择鹞落坪自然保护区所在省份安徽省及其相邻省份江苏省,采用支付意愿法进行了支付意愿的问卷调查,对该保护区的非使用价值作定量评估。评估结果表明,鹞落坪自然保护区的非使用价值为198039.4万元·a-1,其中存在价值为106941.3万元·a-1,遗产价值为59411.8万元·a-1,选择价值为31686.3万元·a-1;江苏省和安徽省样本的平均支付意愿值(WTP)分别为42.0和14 4元·a-1;社会经济各因素与样本的支付意愿率及WTP之间的相关性在不同地区调查的结果有较大差异;对评估结果的敏感性分析显示,本次调查存在年龄和收入敏感性,存在教育程度不敏感性。

The contingent valuation method(CVM)is applied in assessing the non-use value of the Yaoluoping national nature reserve.The study shows that the non-use value in Anhui Province is reckoned at 485.7 million yuan·a^(-1) and at (1 494.7) million yuan·a^(-1) in Jiangsu Province,totaling 1 980.4 million yuan·a^(-1) in sum,of which its existence value is (1 069.4) million yuan·a^(-1),its heritage value 594.1 million yuan·a^(-1),and option value 316.9 million yuan·a^(-1).And the mean WTP is estimated at 42.0 yuan·a^(-1) and 14.4 yuan·a^(-1) for Jiangsu and Anhui subjects,respectively.The results manifest that the survey is of operation significance due to the GDP difference between Jiangsu and Anhui provinces.Correlation of various socio-economic factors with the WTP rate of the subjects and the mean WTP varied from region to region.Sensitivity analysis shows that the survey is sensitive to age and income.Annual income and payment mode play a more significant role affecting amount of WTP,while age and education degree affect rate of WTP.To sum up,the study results provide an important reference for the government to make proper decisions and fiscal budget,and the CVM method confirms that regional difference exists between mean WTP,hence the total WTP.
