摘要: 低碳农业是当前农业发展领域的研究热点与前沿, 但目前关于低碳农业效益综合评价研究鲜有报道。本文以位于闽北地区的福建省南平市炉下镇为研究对象, 探讨构建低碳农业效益综合评价体系的意义, 采用层次分析法(AHP)、特尔斐法(Delphi)和模糊综合评价(FCE)相结合的方法对闽北地区低碳农业效益进行综合评价, 以期实现对低碳农业效益由定性描述到定量评价的转变。通过筛选评价指标、确定指标权重、计算评价指标值, 形成了一个具有3个层次、20个具体指标的低碳农业效益综合评价体系。对炉下镇低碳农业效益进行了实证评价应用, 结果显示: 该地区低碳农业发展取得了良好的综合效益, 低碳农业效益综合评价值为0.723 9, 生态效益、社会效益和经济效益的指标值分别为0.698 2、0.592 3和0.472 0。应用结果表明, 该体系适应于闽北地区低碳农业效益综合评价, 对低碳农业发展具有重要指导意义。Abstract: Low carbon agriculture is a hot issue in modern agricultural research. However, comprehensive evaluation of the benefits of low carbon agriculture is limited. This paper analyzed the significance of constructing comprehensive evaluation system of the benefits of low carbon agriculture. The analytic hierarchy process (AHP), Delphi method and fuzzy comprehensive evaluation method were used to evaluate the benefits of low carbon agriculture with the aim of shifting from qualitative to quantitative evaluation system, using Luxia Town in Nanping City, Fujian Province as a case study. The comprehensive evaluation index system of low carbon agriculture benefit (consisting of 3 first-level and 20 second-level indices) was built based on selected evaluation weight indices as well as on calculated indices. It was then applied to evaluation of low carbon agriculture benefits in Luxia Town. The result showed that low carbon agriculture gained overall benefits in the region. The compressive benefit score was 0.723 9 and the index scores of ecological, social and economic benefits were 0.698 2, 0.592 3 and 0.472 0, respectively. The above results suggested that the index system was suitable for evaluating low carbon agriculture benefits in north Fujian. The study provided a useful base for low carbon agriculture production practice in China.
