中文摘要:用湛江市日平均、旬平均、月平均气象资料,以6种方法计算参考作物蒸发蒸腾量,并以FAO56 Penman-Monteith公式计算结果为标准,评价其他方法在湛江的适用性。结果表明:Hargreaves-Samani方法的年平均参考作物蒸发蒸腾量与FAO56 Penman-Monteith没有显著差异;月平均参考作物蒸发蒸腾量,除个别月份外,其他5种方法与FAO56 Penman-Monteith方法都有显著差异;不同方法计算结果与FAO56 Penman-Monteith法的均方偏差不同的时间尺度表现不同,日值计算,1948 Penman方法最小,Irmark-Allen次之;旬值计算,1948 Penman方法最小,Hargreaves-Samani、Irmark-Allen次之;月值计算Hargreaves-Samani最小,1948 Penman次之。1948 Penman、FAO24 Penman与FAO56 Penman-Monteith法的相关系数较大,Priestley-Taylor、Irmark-Allen次之,Hargreaves-Samani法的较小。

外文摘要:Based on the meteorological data of Zhangjiang, reference crop evapotranspiration were calculated by six different methods. Penman-Monteith method is taken as the standard; applicability of other methods is evaluated. The results show that annual mean reference crop evapotranspiration of Hargreaves-Samani and FAO56 Penman-Monteith is no significant difference. Mean monthly reference crop evapotranspiration of five methods and FAO56 Penman-Monteith have significant difference except specific month. The mean square deviations of ET0 between five methods and P-M method show difference with time scales. The mean square deviations of daily ETo between 1948 Penman and P-M method is least, the following is Irmark-Allen. The mean square deviations of ten days ETo between 1948 Penman and P-M method is least, the following are Irmark-Allen and Hargreaves-Samani. The mean square deviations of monthly ETo between Hargreaves-Samani and P-M method is least, the following is 1948 Penman. Correlation coefficient of 1948 Penman, FAO24 Penman and FAO56 Penman-Monteith are the most volumes, that of Priestley-Taylor, Irmark-Allen are in middle, that of Hargreaves-Samani is the smallest volume.
