摘　　要：用水量核算方法是最严格水资源管理制度实施的一项技术支撑。以山东济宁市梁山县为研究区,采用FAO(国际粮农组织)推荐的Penman-Monteith公式,计算了该县3种主要农作物的逐日作物需水量及净灌溉需水量。研究中考虑到研究区的作物种植面积、灌溉水利用系数等因素提出理论需水量和折算系数的概念,通过推求理论需水量与实际用水量的折算系数,对2011年和2012年梁山县灌溉用水量统计数据进行核算,核算的相对误差分别为0.08%和-1.52%,核算结果较好。The check method of water consumption is a technical support for the strictest water resources management system.In this paper,the Penman-Monteith equation recommended by FAO was adopted to calculate the daily crop water requirement and net irrigation water demand for the three main crops in Liangshan County of Jining City in Shandong Province.The factors such as crop planting area and irrigation water use coefficient were considered in this study and the concepts of theoretical water use and conversion coefficient were proposed.Through the calculation of the conversion coefficient between the theoretical and actual water use,the irrigation water consumption results were checked for 2011 and 2012in Liangshan County.The relative errors were 0.08% and-1.52%,respectively,indicating that the check results are accurate.
