| 摘 要： | 根据不同气候区4个站的历史数据,选取8种基于辐射的PET估算方法,以FAO56-PM法计算的PET作为参考值进行比较分析,最后用20 cm蒸发皿蒸发量对所有方法在不同气候区的适用性进行评价.其结果表明,采用初始参数时,Hargreaves法在不同气候区估算的逐月以及多年月平均PET误差均较小,其它方法则产生较大误差.校...

| Abstract: | Potential evapotranspiration is an important component of the hydrological cycle and a key input to the hydrological models.Estimation of potential evapotranspiration accurately is of great significance for water resources planning and management,important to improve the utilization of agricultural water resources,and helpful to estimate the ecological water requirements,etc.A variety of potential evapotranspiration estimation methods have been developed in the world,but most of them are only suitable for t... |
