摘要: 应用FAO Penman-Monteith公式、Priestley-Taylor公式、Makkink公式、Penman公式和FAO-24 Blaney-Criddle公式等5种方法计算了奈曼地区的参考作物蒸散量,对5种方法的计算结果进行了比较研究,结果表明Penman公式和FAO-24 Blaney-Criddle公式得到的参考作物蒸散量与FAO Penman-Monteith模型结果相近,Priestley-Taylor公式和Makkink公式的计算结果偏差较大,导致不同模型计算偏差的原因是5种模型各自选用了不同的辐射项和动力项计算式。

关键词: 奈曼, 参考作物蒸散量, 计算方法

Abstract: The reference evapotranspiration was estimated by using the FAO Penman-Monteith equation, Penman equation,Priestley-Taylor equation,Makkink equation and FAO-24 Blaney-Criddle equation respectively in Naiman, Inner Mongolia. The results were compared and show that the reference evapotranspiration estimated by the Penman and FAO-24 Blaney-Criddle has a good agreement with FAO Penman-Monteith estimates, but Priestley-Taylor and Makkink estimates are obviously deviated from FAO Penman-Monteith estimate. The cause of the deviation is the difference in calculating the radiation and dynamics.

Key words: Naiman, reference evapotranspiration, calculation methods
