中文摘要	基于19512012年宁夏回族自治区24个气象站气象资料,运用Penman-Monteith模型计算参考作物蒸发蒸腾量(ET_0),并分析ET_0的时空变化。结果表明,宁夏全区ET_0以中部干旱带为最大,南部山区最小,全区多年平均ET_0为889mm/a。ET_0年内分配差异较大,月ET_0最大值出现在6月(130.19mm);月ET_0最小值则出现在12月(25.48mm),极值比达4.11。各分区ET_0变化过程相似,南部山区ET_0明显最低,中部干旱带ET_0最高,且ET_0年际变化强度不大,变异系数较小,极值比均小于0.5。
英文摘要	According to the meteorological data in 24stations of the Ningxia Hui Autonomous Region from 1951to 2012,the reference crop evapotranspiration(ET_0)was calculated using the Penman-Monteith equation, and the temporal and spatial characteristics were analyzed.The results showed that in Ningxia, the top of ET_0 appeared in central arid zone and the lowest was in southern mountain area,and the multiyear average ET_0 in the whole Ningxia was 889mm/a.The distribution of ET_0 in a year was not even,the top of monthly ET_0 was 130.19mm in June,the minimum was 25.48mm in December,and the extreme ratio was 4.11.The changes of ET_0 each area were similar with the lowest in southern mountain and the top in central arid zone,and annual ET_0 changing slightly,whose coefficient of variation was smaller and the extreme value ratio was less than 0.5.
