| 摘 要： | 本文论述了彭曼—蒙特斯(Pcnman—Montcith)模式的推导过程,分析了产生计算误差的四个原因。对模式中参数的取值进行了讨论,分别比较了考虑和不考虑气压订正与空气层结稳定性订正时计算值的差异,结果表明不考虑气压订正时的计算值比实测值偏小10％～20％,而空气层结稳定性订正对计算结果的影响不如气压订正的显著。

| Abstract: | This paper deals with the deducing process of Penman-Monteith and also analyses four factors causing errors in calculations. The values of parameters in the model arc discussed , and also, a comparison is made of difference of calculated values with and without taking air pressure calibration into account and air layer stable calibration. The results show that the calculated values without taking air pressure into account are 10% -20% smaller than the actual, measured ones, while air-layer stable calibration has less significant effect upon the calculated results than those by air pressure calibration. |
