Abstract: .In this paper,the Et of broad-leaved Korean pine forest on Changbai Mountain was determined by water balance method,and calculated by Bowen ratio energy balance (BREB) method in July,August and September,2001. The total Et was 288.18 mm and 214.94 mm,respectively,and the daily average Et in each month was gained,while the rainfall is 301.9 mm. Furthermore,the daily Et and hourly Et rate were computed by BREBmethod,and the availability and precision of the Et determined by water balance and calculated by BREBmethod was discussed.
