摘要
根据青海湖附近气象站的器测资料,结合高原咸水湖的实际特点对彭曼公式进行修正,计算了青海湖的水面蒸发.结果表明:青海湖多年平均(1960-2006年)蒸发量为924.3mm,47年中最高为1,066.2mm(1979年),最低为761.1mm(1989年).考虑了水下热通量对湖面蒸发的影响更能体现湖泊水体蒸发的实际情况.
The monthly and annual evaporation of Qinghai Lake are calculated from 1960 to 2006 on the basis of meteorological data from weather stations around it with mended-and-extended Penman formula according to characteristics of the plateau lake.The results show： the average value of 47 years is 924.3mm,ranging from 761.1mm in1989 to a maximum 1066.2mm in 1979.It is more exact considering the impact of the underwater heat flux on the water body.
