摘要
20 0 1年 7～ 9月应用水量平衡法对长白山阔叶红松林蒸散量进行了测定 ,同时应用波文比(BREB)法对其蒸散量进行了估算 .两种方法得到的总蒸散量分别为 2 88.18mm和 2 14 .94mm ,均小于该时段的降雨量 30 1.9mm .通过两种方法分别得出了各月平均日蒸散量 ,并通过第二种方法计算出了每日的蒸散量及每日不同时刻的蒸散速率 .从而对水量平衡法和BREB方法测算阔叶红松林蒸散量的可行性及其精度进行了验证 .
.In this paper,the E t 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 E t was 288.18 mm and 214.94 mm,respectively,and the daily average E t in each month was gained,while the rainfall is 301.9 mm. Furthermore,the daily E t and hourly E t rate were computed by BREB method,and the availability and precision of the E t determined by water balance and calculated by BREB method was discussed.
