| 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Penm an-Monte ith公式和FAO-Monte ith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Penm an-Monte ith公式计算南方地区参照作物潜在腾发量是合适的。

| Abstract: | Due to the spatio-temporal heterogeneity of meteorology,landform and physiognomy,different reference crop evapotranspiration 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 concludes that it is advisable to Calculate Reference Crop Evapotranspiration(RCE) by means of the standardized Penman-Monteith formula in the southern area of China. |
