摘　　要：基于国际上新近提出并日益得到广泛应用的能值理论,提出了从能量流的角度评价农地整理的生态效益,建立了同社会经济效益评价直接的关联。主要通过对产品和服务功能产出能值变化进行对比分析,从而形成对农地整理项目的综合价值判断。对孝感市孝南区陡岗镇农地整理项目生态效益进行评价,结果表明:该项目的实施使得项目区的自然环境系统的无偿能值投入量大增,资源配置效率得到较大的程度的提高,大大改良了农业生态环境。Based on emergy analysis theory that was newly proposed and widely used in the world, it was proposed that the ecological benefits of rural land consolidation should be evaluated from the angel of energy flow. The direct link with the social-economic benefit evaluation was set up. The comparative analysis was carried on the emergy changes of the products and services output. The comprehensive value judgment of the rural land consolidation project was formed. The ecological benefits of rural land consolidation project in Dougang Town of Xiaonan District in Xiaogan City were evaluated. The results showed that the implementation of the project increased the free emergy input of the natural environment system in the project area, enhanced the resource allocation efficiency greatly and greatly improved the agricultural ecological environment.
