气象数据缺测条件下参照腾发量的计算方法

Calculation methods for reference evapotranspiration with limited weather data

利用河北雄县和望都两气象站的数据 ,对FAO推荐的气象数据缺测时参照腾发量的计算方法进行了检验和评价 ,分析了参照腾发量对各气象要素的敏感性 。

The alternative methodologies for calculation of reference evapotranspiration ET 0 are tested and evaluated when some of the weather data are missing,using daily data from Xiongxian and Wangdu,Hebei province.The sensitivity of the climate factors for ET 0 is analyzed.The alternative methods for calculation of reference evaportranspiration according to limited weather data appropriate to North China are proposed.
