| 摘 要： | 研究西部农户耕地保护生态外部性价值对科学合理地制定耕地保护经济补偿政策具有重要的参考意义。基于耕地面积建构耕地保护生态外部性价值计量模型，利用西部省区2005—2012年的相关数据，对西部农户耕地保护生态外部性价值进行实证研究。结果表明:西部农户在保护耕地过程中向社会无偿提供的生态外部性价值量平均为8 174元/（hm2·a），各省区农户贡献的耕地生态外部性年价值量具有不确定性、区域差异性，整体上呈增长变化。因此，从西部区域角度建立西部农户耕地生态外部性价值的补偿标准与机制具有必要性、可行性。

| Abstract: | It has important reference significance for the policy of scientific and reasonable economic compensation farmland protection to study the externality of cultivated land ecological value protected by farmers in China western provinces. The built measurement model of the externality of ecological protection value based on cultivated land area in the western provinces and the data of the western provinces and regions from 2005 to 2012, was used to make empirical research on it. The results show that the externality ecological value freely provided to the public by farmers in the course of cultivated land protection averages 8 174 yuan per hectare each year in the western region of China; the inter-provincial interannual variability of farmland ecosystem externality value is uncertain and regional differences. The overall assumed the growth change; it was necessity for the farmers to establish the ecological benefit compensation mechanism of cultivated land externality in China western provinces. |
