中文摘要	参考作物蒸散量不同计算方法在极端干旱的塔克拉玛干沙漠腹地的适用性鲜有研究。依据塔克拉玛干沙漠腹地收集的20052010年的气象资料,以Penman-Monteith 为标准,运用8种参考作物蒸散量不同计算方法,探讨在塔克拉玛干沙漠腹地的适用性及计算结果的差异性。结果表明: 在极端干旱的塔克拉玛干沙漠腹地,Penman1948、FAO24-Penman、Irmark-Allen、Makkink、Priestley-Taylar 计算结果偏小,而FAO Penman 修正法计算结果偏大,仅Kimberley Penman 和Hargreave 与Penman-Monteith 的计算结果没有显著差异。以2004年312月气象资料检验Penman1948、FAO24-Penman、Irmark-Allen、Makkink、FAO Penman 修正法和Priestley-Tayla 修正公式,计算结果与Penman-Monteith 月偏差仍然较大。偏差较大的原因是3种Penman 计算方法均采用了不同的风速修正方法,由风速引起的空气动力项所占的参考作物蒸散量月贡献率不同,而Irmark-Allen、Priestley-Taylar 和Makkink 3种方法仅考虑了辐射项,忽略了空气动力项。因此,这6种计算方法在极端干旱的塔克拉玛干沙漠不适用,仅有Kimberley Penman 和Hargreave 可以适用。
英文摘要	As a measurement of soil-plantation-atmosphere transfer system model,the reference crop evapotranspiration(ET_0),which affects the application of models and the precision of prediction,has traditionally been used for understanding water use and water consumption of plant. In order to test the applicability of different methods for hinterland of the Taklimakan Desert,Penman-Monteith method was taken as the standard to calculate the values of ET_0 with eight methods of reference crop evapotranspiration at Tazhong Meteorological Station in hinterland of the Taklimakan Desert during the period of 2005-2010. The results showed that the annual ET_0 calculated with Penman1948, FAO24-Penman,Irmark-Allen,Makkink and Priestley-Taylar were lower than that calculated with Penman-Monteith method,and that calculated with the modified FAO Penman was slightly higher than that calculated with Penman-Monteith method,and there was no significant difference between the results calculated with the Kimberley Penman,Hargreave and Penman-Monteith methods. The deviation of ET_0 calculated with Penman1948, FAO24-Penman,Irmark-Allen,Makkink,Modified FAO Penman and Priestley-Taylar was higher than that calculated with Penman-Monteith method. There was a high deviation because the different modified wind speed formula were used in the calculation with three Penman methods (Penman1948,FAO24-Penman and Modified FAO Penman),and the radioactive term was considered only in the calculation with other three methods (Irmark-Allen, Makkink and Priestley-Taylar),but the aerodynamic term was ignored. Therefore,these six methods (Penman1948, FAO24-Penman,Modified FAO Penman,Irmark-Allen,Makkink and Priestley-Taylar) of ET_0 was inapplicable for the extremely arid Taklimakan Desert expect the Kimberley Penman and Hargreave methods.
