摘要
本文提出和建立了一个计算蒸散发能力和饱和湿润表面蒸散发量的经验公式,并把互补相关模型应用到湖北省十六个流域,江汉平原水网区和东湖的蒸散发估计。模型的计算值同水量估计值以及蒸发的研究和计算提供了另一条简便易行的途径。
The complementary relationship evapotranspiration theory and models are discussed and ex plored. Based on the long.- term observed solar radiation, evaporation and meteorological data in Hubei Province, the formulas for calculating potential and wet surface evapotranspiration are proposed and established. Morton models(CRAE,CRWE and CRLE) are modified and used to estimate catchment evapotranspiretion and lake evaporation. It is shown thaqt the model estimaters are very close to the Pan data and water balance estimator. The modified models provide a fairly reliable estimate of monthly and annual evaporation. The complementary relationship theory provides another way for the resea ch and the estimation of evapotranspiration.
