| 英文摘要 | Regional evapotranspiration is an important component of the hydrological cycle. However. reliable estimates of regional evapotranspiration are extremely difficult to obtain. In this study, the evapotranspiration simulated by three complementary relationship approaches, namely the Advection-Aridity (AA) model, the Complementary Relationship Areal Evapotranspiration (CRAE) model and the Granger (G) model. is evaluated With the observations over the Yellow River basin during 1981-2000. The simulations on overall annual evapotranspiration are reasonably good. with mean annual errors less than 10% except in extreme dry Years. The AA model gives the best estimation for the monthly evapotranspiration, and the CRAE and GM models slightly overestimate in winter. In addition, the AA model presents the same closure error of water balance over the Yellow River basin as model G. which was less than that by the CRAE model. In rather dry and rather wet cases (with higher or lower available energy). all three models perform less well. Empirical parameters of these models need to be recalibrated before they can be applied to other regions. The distribution of evapotranspiration over the Yellow River basin is also discussed.
