| 摘 要： | 根据一种简化的Penman模型,建立了一个无需风速的参考作物蒸散发模型(Penman-Valiantzas模型),在此基础上又结合Hargreaves辐射方程建立了无需风速和日照时数的Penman-Valiantzas-Hargreaves模型.利用世界粮食组织的CLIMWAT数据库中156个气象站点多年月平均资料对此...

| Abstract: | A Penman-Valiantzas model is developed based on the Valiantzas approach for estimating reference evapotranspiration in China without wind speed data.Besides,the Hargreaves radiation equation is used for deriving a Penman-Valiantzas-Hargreaves model,in which only the relative humidity and the air temperature are required as the model input.The two new models are tested with the CLIMWAT database of UN Food and Agriculture Organization(FAO).A total of 156 Chinese stations are extracted from the database,which ... |
