Abstract: 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.
