摘　　要：针对传统方法计算农业灌溉效益时无法衡量自然环境对农作物生产影响的缺陷,以连云港市农作物生产系统为例,采用能值理论及其统一衡量标准将决定灌溉效益的主要指标转化为同一量纲,定义了灌溉效益分摊系数,构建了农业灌溉效益能值指标体系并分析了影响因素,为灌溉效益准确计算提出了具体方案。This article overcomes the defect of traditional method for ealeulation agriculture irrigation benefit, which is unable to judge the impact of nature environment on crop production. Taking the crop production system of Lianyungang City for an example, energy value theory and its uniform criterion are applied to convert the main index of irrigation benefit to the same dimensional parameters. Sharing coefficient of irrigation benefit is defined and all indexes influencing agriculture irrigation benefit are analyzed, which provides the specific method to improve the accuracy of irrigation benefit.

关 键 词：能值理论 农业灌溉效益 灌溉效益分摊系数 农作物生产系统
