摘要：基于1961—2013年贵州19个气象站点观测资料,以FAO56 Penman-Monteith(P-M)方法为标准,分析了Imark-Allen、Hargreaves-Samani、McCloud、Priestley-Taylor、 Makkink、Thornthwaite等6种参考作物蒸散量估算方法在贵州省的适用性,并利用经验系数对6种方法进行修正。结果表明:修正前,年尺度上McCloud、Thornthwaite法与P-M法十分接近,应用前景较好,Priestley-Taylor法适合在季节和月尺度上的估算,Imark-Allen、Hargreaves-Samani、Makkink法的偏差较大,适用性较差。修正后Imark-Allen、Hargreaves-Samani、McCloud、Priestley-Taylor、Makkink法的适用性提高,修正后Thornthwaite法适用性仍不高。利用经验系数对这些方法进行修正可以较好地提高估算精度。
Based on the observed data of 1961-2013 obtained from 19 meteorological stations in Guizhou Province,the applicabilities of six methods(i.e.Imark-Allen,Hargreaves-Samani,McCloud,Priestley-Taylor,Makkink,Thornthwaite)for estimating the reference crop evapotranspiration in Guizhou Province are analyzed herein by taking the method of FAO56 Penman-Monteith(P-M)as the standard,and then the six methods are modified with the relevant empirical coefficient.The result shows that before the modifications,the methods of McCloud and Thornthwaite are very close to P-M method on annual scale and their application prospects are better and Priestley-Taylor method is suitable for the estimations made on seasonal and monthly scales,while the deviations from the methods of Imark-Allen,Hargreaves-Samani,Makkink are larger,thus their applicabilities are poor.After the modifications,the applicabilities of the methods of Imark-Allen,Hargreaves-Samani,McCloud,Priestley-Taylor and Makkink are enhanced,but the applicability of the method of Thornthwaite is still not high enough.Better estimation accuracies can be obtained from the modifications made on these methods with the empirical coefficient.
