      耕地重金属污染治理生态补偿标准条件估值法研究--以广西大环江流域为例

      Study on Eco-Compensation Standard for Remediation of Heavy Metal Polluted Farmland With CVM:A Case Study of the Dahuanjiang River Valley, Guangxi

      摘要:
      运用条件估值法,于2015年8月对广西环江县大环江流域重金属污染地区农户受偿意愿进行调查研究。结果表明,研究区农户对当地耕地重金属污染治理项目的参与意愿与投标额度(设计补偿标准)、家庭耕地面积和耕地受污染程度呈正相关关系;农户平均受偿意愿下限为12630?75元·hm-2·a-1,该测算值可为当地耕地重金属污染治理生态补偿标准的确定提供理论依据。认为广西环江县大环江流域耕地重金属污染治理及其配套生态补偿项目应首先选择耕地面积较大且污染较明显地区作为项目选址。建议在今后的生态补偿研究中注意补偿标准与客观条件之间的联系,并制定出一套具有普适性的生态补偿标准研究方法。
      Abstract:
      A field survey of willingness of farm households to get compensation of heavy metal pollution of farmlands was conducted using the contingent valuation method ( CVM) in August 2015 in the Dahuanjiang River Valley in Huanjiang County, Guangxi. Results show that willingness of a farmer house hold to participate in the local soil remediation project is positively related to designed compensation standard, area of the farmland cultivated by the farmer household, and pollu?tion degree of the farmland. On average, farmer households would accept compensation no less than 12 630?75 CNY · hm-2 ·a-1 , which can serve as a theoretical basis for designing of standards for ecological compensation for remediation of heavy metal polluted farm lands in the valley. It is held that the remediation of heavy metal polluted farmlands and matc?hing eco?compensation projects should begin with regions quite large in area of markedly polluted farmland. It is, therefore, suggested that in future studies on eco?compensation, attention should be paid to the relationship between compensation standards and objective condition and formulation of a universal set of methods for studies on eco?compensation standards.
