英文摘要	Three methods of calculating evapotranspiration (ET), Penman-Monteith (PM), Makkink (MK) and Priestley-Taylor (PT) equation, were applied to a temperate meadow in Inner Mongolia, China. We compared these methods with eddy covariance (EC) method. The results indicated that a reduction in mean absolute error (MAE) and root mean squared error (RMSE) was achieved for MK and PT methods (45.6-83.0%) when using site-specific parameters compared with referenced ones, but an increase of 75.9-93.9% for PM method. Intercomparison of three methods through comparison with EC measurements indicated that PT method with site-specific parameters performed the best to estimate ET, followed by PM method with referenced parameters, and then MK equation with site-specific parameters (overestimate ET by 8.2, 12.1, 16.5% and 3.4, 12.8, 21.0% respectively for half-hourly and daily values).
