基于选择实验法的生态景观非市场价值研究——以徐州云龙湖为例

Research on Non-Market Value of Ecological Landscape Based on Selection Experiment:Taking Yunlong Lake in Xuzhou as an Example

以徐州云龙湖景区为调研地,研究其核心景观资源云龙湖的非市场价值。基于效用理论、消费者偏好理论,通过选择实验法设计问卷,分析了不同特征的受访者对景区内景观的感知差异,构建了多项LOGIT模型来评估云龙湖的非市场价值。结果表明:云龙湖现有观赏状态下的非市场价值为每人次8.01元;湖水能见度提升至1~2 m时,受访者的意愿支付提升至每人次8.75元;湖水能见度大于2 m时,受访者的意愿支付提升至每人次10元。

This paper takes scenic area of Yunlong lake as the research area and studies the nonmarket value of Yunlong lake as the core landscape resource.Based on utility theory and consumer preference theory,the questionnaire is designed by selecting experiments to analyze the perception differences of respondents with different characteristics in the landscape area,and multiple LOGIT models are constructed to evaluate the non-market value of Yunlong lake.The results show that the non-market value of Yunlong lake is 8.01 yuan per capita.The willingness to pay increasing to 8.75 yuan per capita when the lake visibility increases from 1 to 2 meters,and the willingness to pay increasing to 10 yuan per capita when the lake visibility is higher than 2 meters.
