摘要
文中基于环境价值评估法(CVM)为干旱区绿洲农田土壤重金属污染防治生态补偿政策进行了计量经济学的模型分析,测算了农户对当地实施生态补偿的受偿意愿。在382个调查样本中,91.79%的受访村民认为所在地目前土壤污染问题十分严重并已造成了食用人群健康风险,制定合理的生态补偿标准是保障生态修复工程的核心因素。受偿意愿调查结果显示,干旱区绿洲农田受重金属污染的农户的年平均受偿意愿(MWPA)在746.45-862.73元/hm2之间,影响该数额的主要因素为农户家庭人口、户均耕地面积以及农户受教育程度。该结果说明受访农户提出的受偿意愿是以当地种植基本粮食作物的年收入840元/亩为基础的,但未包括当地农业生产的生态效益损失和对人群健康影响的损失,且受经济欠发达地区农户年均收入较低和信息获取渠道缺乏的影响,当地农户受偿意愿低于其他地区生态补偿受偿意愿。
In this paper,the contingent valuation method（CVM） was used to analyze the farmers＇ willingness to accept（WTA） the compensation for recovering the heavy metal contaminated soil in arid oasis areas,using Baiyin and Jinchang suburb farmland as a case study.Based on the result of statistical analysis of 382 questionnaires,it was showed that 91.79% of farmers in this area have recognized the impact of soil contamination.41.62% of respondents were against to abandon the contaminated cropland because of less life safeguard,so reasonable compensation standard in ecological restoration project is an important issue.Econometrics model analysis indicated the farmers＇ willingness to accept（WTA） were between 746.45-862.73 Yuan（RMB） /hm2.The acute WTA data had a positive relationship with the family population,education and the areas of the cropland.The farmers＇ gender,age and their income had little affection on WTA.The results showed that the farmers＇ WTA was based on the income of crops planting which was 840 Yuan（RMB） /hm2 pre year in this areas.
