基于耕地非市场价值的三峡库区消落带生态休耕补偿标准研究

Economic Compensation Criteria of Eco-fallow Based on Non-market Value of Cultivated Land in Water-level Fluctuation Zone of Three Gorges Reservoir Area

[目的]对三峡库区消落带耕地非市场价值进行评估,为生态休耕经济补偿标准的厘定提供参考。[方法]通过双边界二分式CVM法开展评估和分析。[结果](1)受访者基本可以构建起CVM假想市场,问卷理解度调查显示受访者的理解度达84.73%,调查可信度较高。(2)受访者支付意愿存在较大差异,农户愿意支付率达到75.65%,城镇居民愿意支付率仅占到64.80%。(3)Probit回归模型与Logit回归模型分析表明,收入状况是影响受访者支付意愿的主要因素。[结论]以受访者单位耕地支付意愿1 516.76元/(hm^2·a)作为该区的生态休耕经济补偿标准,则所涉及的三峡库区9区县消落带耕地的非市场价值约为30.15亿元。

[Objective] The low compensation leads to extensive cultivation on hydro-fluctuation belt, which continue to affect the water environment in the reservoir area. The compensation criteria should be redefined based on the value of cultivated land resources. [Methods] We adopt double-bounded dichotomous contingent valuation method（CVM） to evaluate the non-market benefits of cultivated land in the water-level fluctuation zone of Three Gorges Reservoir area, which is to provide reference for economic compensation criteria of eco-fallow. [Results] （1） The interviewees are basically able to build up the CVM hypothetical market, and the reliability of survey data is high because the questionnaire survey showed that interviewees＇ understanding level reached 84.73%. （2） The interviewees＇ willing to pay（WTP） is obviously different between households and urban residents, the former＇ s WTP is 75. 65% but the latter＇ s WTP is only 64. 80%. （3） The Probit regression model and Logit regression model analysis showed that income is the main factor affecting the interviewees＇ WTP. [Conclusion] We take the interviewees＇ WTP 1 516.76 yuan/（hm2· a） as economic compensation criteria of eco-fallow in this area, so the non-market benefits of cultivated land is 3. 015 × 10^9 yuan in the research area.
