Abstract EN
Actual evapotranspiration was observed by using eddy covariance (EC) technique, calculated by micrometeorological method the Bowen ratio energy balance (BREB) and measured by micro-lysimeter (ML) in the Suli alpine meadow which located in the northeastern edge of Qinghai-Tibet Plateau noted for its high elevation and cold environment during the growing season in 2011.
Results showed that the energy balance ratio for half-hour data was 0.74.
Without consideration of uncertainty, the evapotranspiration values estimated by BREB, ML, and EC were 270.6 mm, 238.9 mm, and 236.1 mm, respectively.
Significant correlation existed between the evapotranspiration results by the three methods.
Uncertainties of the evapotranspiration estimation by BREB, ML, and EC were 19.6 mm, 15.6 mm, and 15.1 mm, respectively.
Deduced by facts on the natural and vegetation conditions, the value of evapotranspiration should be equal to that of precipitation, that is, about 252 mm.
From this point, the evapotranspiration values estimated by the three methods were within a reliable range.
The EC method has larger advantage and wider scope for the estimation of evapotranspiration in alpine meadow area.
