摘　　要：为分析不同参考作物蒸散量估算方法在淮北平原的适用性,以FAO56 Penman-Monteith(FAO56PM)模型为标准,基于五道沟实验站2009-2022年气象观测数据,选取6种统计指标,从日、月尺度综合分析。结果表明,所有方法中,日尺度下FAO24Penman(FAO24PM)法、1996 KiM-Berly Penman(K-P)法、Pristley-Taylor(P-T)法最优,月尺度下FAO24PM法、P-T法、Debruin-Keijman(D-K)法最优;综合法最优,其次依次为辐射法、质量传输法和温度法;综合法中FAO24PM法最优,辐射法中P-T法最优,温度法中FAO24BC法最优,质量传输法中Mahringer法日尺度下最优,Trabert法月尺度下最优。因此,当数据资料充足时推荐FAO24PM法,资料不齐全时推荐P-T法、FAO24BC法、Mahringer法(日尺度)或Trabert法(月尺度)。To analyze the applicability of different reference crop evapotranspiration estimation methods in the Huaibei Plain,based on the meteorological observation data of Wudaogou Experimental Station from 2009 to 2022,this paper takes the calculation results of FAO56 Penman-Monteith(FAO56PM)method as the standard and select six statistical indicators for comprehensively analysis from daily and monthly scales.The results showed that the FAO24 Penman(FAO24PM)method,1996 KiM-Berly Penman(K-P)method and Pristley-Taylor(P-T)method were the best at the daily scale,and the FAO24 PM method,P-T method and Debruin-Keijman(D-K)method were the best at the monthly scale.The comprehensive method shows the highest performance,followed by the radiation-based method,the mass transfer-based method and the temperature-based method.The FAO24 PM method is the best in the comprehensive method.The P-T method is the best in the radiation-based method.The FAO24 BC method is the best in the temperature-based method.The Mahringer method is the best in the mass transfer-based method at the daily scale,while the Trabert method is the best at the monthly scale.Therefore,the FAO24PM method is recommended when the data are sufficient,and the P-T method,FAO24BC method,Mahringer method(daily scale)or Trabert method(monthly scale)are recommended when data are insufficient.
