Comparison of Different Methods for Calculating Evapotranspiration of Crops in the Yellow River Delta [PDF]
, 2017 准确估算各地区的参考作物腾发量(ET_0)是农业灌溉设计和节水规划中必不可少的内容。利用黄河三角洲地区4个典型气候区的气象资料,选用5种计算方法(P-M, FAO-79Penman、Priestley-Taylor,FAO-24Penman和 Hargreaves-Samani)计算了 ET_0,并以P-M方法作为标准,对其他方法进行了评价。结果表明,在黄河三角洲各气候区FAO-Penman法估算的ET_0较Priestley-Taylor方法更接近于P-M法的计算结果,并且计算精度较高,误差在3 ...
