摘要:

在测定该区2000—2005年气象因子的基础上,分析研究了乌兰布和沙漠沙地可能蒸散的月变化特点,比较分析了应用Penman方程、Thornthwaite公式和Holdridge 3种方法计算的可能蒸散。结果指出Penman方程计算的可能蒸散和水面蒸发量具有显著的直线性相关,可应用Penman 方程计算所得的可能蒸散评价该区的水分蒸发特点。研究指出可能蒸散月变化与月平均温度的变化基本一致,全年最大的月份是7~8月,全年累计可能蒸散量为3 041 mm。

Abstract:

The monthly change of the potential evapotranspiration Wills an alyzed based on the meteorological observations during 2000—2005 in the Ulan Buh Desert.The potential evapo transpiration calculated by Penman equation,Thornthwaite formula and Holdridge method were compared and an alyzed,and the result indicated that the potential evapotranspiration calculated by Penman equation WaS conspicuously correlated to the water surface evaporation,and it could be used to evaluate the water evaporation characteristic.Th e re—search showed that the monthly change of the potential evapotranspiration Was similar to the monthly average temperature,the largest value appeared in July and August,and the total potential evapotranspiration in a year Was 3 041 mm.

Key words: Ulan Buh Desert, po tential evapotranspiration, Penman equation
