Abstract: By using contingent valuation method, this paper assessed the non-use value of the ecotourism resources in Wuyishan Nature Reserve based on the questionnaire 1) description of the projects for assessment and their background information, 2) social and economic characteristics of interviewees, 3) attitudes and protection awareness of interviewees to the environment, and 4) willingness of interviewees to pay for the assessed projects. The ways of payment and the reasons of non-payment by the interviewees were analyzed. In the reserve, the non-use value of the ecotourism resources was 6.52×10⁸ Yuan per year, among which, the existence value was 3.38×10⁸ Yuan per year, heritage value was 1.42×10⁸ Yuan per year, and alternative value was 1.72×10⁸ Yuan per year. Through the comparison with previous relevant studies, the validity and reliability of the results were tested. This study could be of significance in promoting the changes of human being’s understanding of ecotourism resources value and making the protection and development of these resources become more scientific and sustainable.
