摘　　要：根据调查资料,规划灌区各种不同年份农作物增产指标或多年平均增产指标确定之后,即可对灌区工程的效益进行分析和计算。文章对我国经常采用的几种灌溉工程效益的计算方法作了简略介绍。According to the investigated materials and after the crops yield increasing targets in various different years or average yield increasing targets of some years in planned irrigated areas have been determined, the analysis and calculation of the benefits of irrigated areas' engineering can be made. This paper introduces briefly some calculating methods for the benefits of irrigation engineering that are adopted in our country commonly.
