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

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。

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

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 3.015×10⁹ yuan in the research area.
