摘要:采用4种常用的腾发量模型(Makkink模型,Turc模型,Priestley-Taylor模型以及Hargreaves模型)计算日腾发量,并以Penman-Monteith FAO 56公式计算结果为标准值进行对比,旨在寻找出建模数据少、模拟精度高以及适合研究区的腾发量计算模型。结果表明:Turc模型的日参考作物蒸发蒸腾量与Penman-Monteith FAO 56差异较小,其次是Makkink模型与Priestley-Taylor模型,Hargreaves模型的差异最大。

AbstractBy using the calculation results of Penman-Monteith FAO 56 as standard values, four models including Makkink model, Turc model, Priestley-Taylor model and Hargreaves model, which were commonly used to estimate daily reference crop evapotranspiration values, were evaluated to determine the suitable model for estimating ET₀ with few data requirements and high accuracy for north Tarim Basin. The results showed that Turc model was the best model in estimating ET₀, followed by Makkink model and Priestley-Taylor model, but Hargreaves model turned out to be the most imprecise model in the study area.
