摘　　要：通过对农作物灌溉增产效益影响因素的分析,提出以作物有效灌溉水量和作物总产量作为计算作物灌溉增产量的主要影响因素,并通过对影响因素的随机特性分析,构造了以时间序列分析法为基础的农作物灌溉增产量与有效灌溉水量和作物总产量的关系,并对由此建立的线性模型进行了显著性检验和模拟性检验.The effective water use of crop irrigation and the general crop production were shown to be the main factors for de-termining the production increase from crop irrigation,based on analyzing the benefits of production increase from crop irriga-tion.A relationship among production increase,effective water use and general production,established by the method of time se-ries analysis,is described in this article.The linear model created on this basis was tested for significance and simulation.
