分析了28年生油松人工林对降水的再分配及林冠容水量与蒸发速率。林冠对降水的再分配是:林冠截留量占17.4%,林内降水量占80.2%,树干径流量占2.4%。林冠容水量为1.12mm,平均蒸发速率为0.18mm/min。
The distribution of 28-year-old Pinus tabulaeformis plantation on precipitation and the capacity and evaporation rate of canopy water were analyzed. Canopy redistribution of precipitation is: canopy interception accounted for 17.4%, forest precipitation accounted for 80.2%, trunk runoff accounted for 2.4%. The water volume of the canopy is 1.12 mm and the average evaporation rate is 0.18 mm / min.
