Abstract

There are different opinions on the applicability of the Hargreaves method in calculating reference crop evapotranspiration (ET0) in arid land. In order to test the applicability of the Hargreaves method in the Taklamakan Desert hinterland, we carried out the current study using the metadata in 2005-2010 collected at the meteorological station in the Taklamakan Desert hinterland. The Penman-Monteith method was set as standard to compare the difference between the two methods. The results showed that at annual scale, the ET0 calculated with the Hargreaves equation was a little higher than that obtained by Penman-Monteith method, the standard deviation were 32.86~35.00 mm, and the annual reference crop evapotranspiration (ET0) presented weak variation; at monthly scale, the reference crop evapotranspiration (ET0) presented a middle variation, the absolute deviation of monthly ET0 was -3.26~8.73 mm between the two methods, and the monthly relative deviation was -12.20%~29.02%, and the ET0 deviations were all not more than 10% except for October and November. It was documented that the difference for the calculating ET0 between the two methods was resulted from the higher temperature range. Based on the estimated ET0 at annual and monthly scales by the two methods, our results indicated that the ET0 calculated with the Hargreaves method was applicable in the extreme arid area of the Taklamakan Desert hinterland.
