国家水利风景区非市场经济价值评估——以沂蒙湖国家水利风景区为例

Assessment ofnon-market economic values of national water parks-Case study of Yimenghu National Water Park

国家水利风景区的建设与管理是实现水生态文明和美丽中国建设的重要内容,对国家水利风景区的保护需要对其非市场经济价值(使用价值和非使用价值)进行评估。运用条件价值评估法的单边界二分式和双边界二分式引导技术,通过问卷调查获取数据,采用logistic、log-logistic、normal和log-normal等4种计量模型,定量评估了沂蒙湖国家水利风景区的使用价值和非使用价值。结果表明:沂蒙湖国家水利风景区具有显著的使用价值和非使用价值;log-logistic和log-normal模型在双边界二分式引导技术下的评估结果更可靠;受访者接受以向非营利性组织捐款的方式参与水利风景区保护。该评估结果可为水利风景区保护政策制定的成本收益分析和相关可持续管理政策的制定提供参考。

The construction and management of national water parks is an important part of realizing water ecological civilization and beautiful China.The protection of national water parks requires an assessment of their non-market economic values(use values and non-use values).Based on the single-bound and double-bound dichotomous contingent valuation method techniques,the use values and non-use values of Yimenghu National Water Park are quantitatively evaluated.Four econometric models containing logistic,log-logistic,normal and log-normal are applied through questionnaire data.The results showed that:(1)The Yimenghu National Water Park is of high use values and non-use values.(2)The evaluated results of log-logistic and log-normal econometric models are more reliable in the double-bound dichotomous CVM technique.(3)The respondents are willing to participate in protection in the form of donations to non-profit organizations.The assessment achievements are helpful for the cost-benefit analysis of the protection and sustainable management policies of water parks.
