| 摘 要： | 采用联合国粮农组织最新推荐的修正Ｐｅｎｍａｎ公式分析计算了霍泉灌区长系列参考作物的腾发量及其变化规律，在此基础上提出了该灌区冬小麦、夏玉米需水量预报模型．分析了预报模型中参数Ａ０的变化规律，并在预报过程中进行调整．运用实测资料检验表明，修正后的模型在逐日作物需水量预报中更符合实际，具有比较高的精度．

| Abstract: | The daily reference evaportranspiration ( ET 0) from 1982 to 1996 in Huoquan irrigation district, Shanxi Province is calculated from the modified Penman equation recommended by FAO (Food and Agricultural Organization of United Nation) in 1991. Based on the change pattern of ET 0, the procedures and mathematical models to forecast the daily ET 0 of wheat and maize evaportraspiration are presented. The case study shows that the principle and models are feasible and simple in use. |
