中文摘要	以新疆焉耆盆地为例,以PM模型计算值为标准,评价了H-S、P-T与McCloud模型在研究区的适用性。结果表明:太阳总辐射与ET_0日值之间呈现极强的相关性(r=0.937)与偏相关性(r=0.962),说明太阳辐射能量是影响ET_0的主要因素;在ET_0日值计算中,H-S模型计算结果显著大于PM模型,P-T模型与McCloud模型计算值显著小于PM模型,其中H-S模型计算精度最高,均方根误差为0.836 mm,平均偏差为0.638 mm;通过对H-S模型、P-T模型与McCloud模型进行修正,不同模型的计算精度均有所提高,修正后P-T模型的计算精度最高(均方根误差RMSE为0.613 mm,纳什效率指数E为0.6821),且3种模型修正后ET_0日值与PM模型计算值均无显著差异。
英文摘要	This paper taking Yanqi Basin as an example, using the calculated ET_0 value by PM model as standard, has evaluated the applicability of H-S, P-T and McCloud models in study area. The results showed that:The total solar radiation with the ET_0 value has shown a very strong correlation(r=0.937) and partial correlation(r=0.962). It explained that the solarradiation energy was the main impact factor to the ET_0. In the calculation of ET_0 value, the calculated result by H-S model was significant higher than the PM model, the P-T and McCloud models were significant less than PM model. Among them, the calculated accuracy was the highest by the H-S model, the, root mean square error was 0.836 mm, the average deviation was 0.638 mm. Through modification to the H-S, P-T and McCloud models, the calculation precision for different models total obtained improvement. The modified P-T model obtained thehighest accuracy (RMSE was 0.613 mm, Nash-Sutcliffe E was 0.6821), theET_0 value by three modified models had no significant differences with PMmodel.
