摘要
受地区间气象、地形和地貌时空异质性的影响,不同参考作物腾发量计算公式适用性各不相同。以湖南省83个站点1971～2000年气象观测资料为样本,论述了Penman-Monteith公式和FAO-Monteith修正式主要方程、参数以及适用范围的差异性。结果表明：根据生育期作物需水特点,运用标准化的Penman-Monteith公式计算南方地区参照作物潜在腾发量是合适的。
Due to the spatio-temporal heterogeneity of meteorology, landform and physiognomy, different reference crop evapotranspirafion methods have different applicability. Based on the meteorological data of 83 stations in Hunan province, the basic equations, main parameters and applicability of Penman-Monteith and Modified FAO-Penman are compared in this paper. Finally, considering water requirement features of southern crops, the thesis coneludes that it is advisable to Calculate Reference Crop Evapotranspirafion （RCE） by means of the standardized Penman-Monteith formula in the southern area of China.
