中文摘要：

为促进提升补偿资金使用的经济效率和健全耕地保护补偿机制,本文在核算补偿效益和参与成本基础上评定耕地保护经济补偿对象,运用效益成本比例方法测算耕地保护经济补偿优先度.研究结果表明慈溪市37227个评价单元的耕地保护经济补偿收益和参与成本呈现明显空间差异,利用快速聚类分析将其分为优先补偿区、次级优先补偿区、次级补偿区和临界补偿区四个补偿级别,其分别占慈溪市耕地总面积的4.309%、17.837%、31.972%和45.882%.研究结论说明耕地保护经济补偿效率存在空间差异,与耕地种植机会成本高度相关,应建立以补偿效率为基准的耕地保护经济补偿对象空间选择机制.

英文摘要：

One goal of this study was to assess and categorize farmland protection areas on the basis of costs and beneifts of economic compensation, so as to enhance the economic efifciency of compensatory fund outlays while simultaneously protecting farmland areas. Compensation priority was ranked using a cost-effective approach. Taking Cixi City, Zhejiang Province, as an example, the entire prefecture was classiifed into four zones based on levels of compensation using a cluster analysis that identified: priority compensation zones, sub-priority compensation zones, secondary compensation zones, and critical compensation zones; the areas of arable land in these zones accounted for 4.309%, 17.837%, 31.972%, and 45.882%, respectively, of the total area of arable land. The study identiifed spatial differences in the efifciency of economic compensation for farmland protection, which were highly correlated with costs of arable cultivation. We suggest that rules of farmland protection selection based on compensation efifciency should be established.
