中文摘要	参考作物蒸散发(ET_0)是计算植被耗水量、分析区域水分平衡、管理水资源的基本参数。由于区域间气象条件的差异,ET_0模型在不同地区表现出不同的适用性。文中以新疆塔里木盆地西缘的阿克苏地区为例,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与偏相关性,说明太阳辐射能量是驱动SPAC系统中水分从植被向大气运动的主要动力; 由于模型输入参数的不同,在ET_0日值计算中,H - S模型、P - T模型与McCloud模型计算值显著小于PM模型,其中以H - S模型计算精度最高,均方根误差为1.058mm,平均偏差为0.212mm; 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McCloud模型的计算精度最高,且3种模型修正后ET_0日值与PM模型计算值无显著差异。文中研究结果可为塔里木盆地西缘地区参考作物蒸散发的计算提供重要参考。
英文摘要	The reference crop evapotranspiration is basic parameters for calculation of vegetation water consumption, analysis of regional water balance,and water resources management. Because of the difference of regional meteorological conditions,the ET_0 model exhibits different applicability in different regions. In this paper,taking Akesu area as an example,using ET_0 value calculated by PM model as the standard,the applicability of H - S, P - T and McCloud model in the study area were evaluated. The results showed that the total solar radiation and ET_0 value had a strong correlation and partial correlation,the sun radiation energy was the main power to drive the water in SPAC system from vegetation to the atmospheric motion; as the input parameters of the model were different,the ET_0 value of H - S model,P - T model and McCloud model were significant less than PM model, in which the H - S model calculation had the highest accuracy,root mean square error was 1.058mm,the average deviation was 0.212mm,the H - S model,P - T model and McCloud model were modified,the calculation precision of different models improved,and the McCloud model had the highest accuracy,ET_0 values of 3 kinds modified models had no significant differences with PM model. The results can provide an important reference for the calculation of ET_0 in western margin of Tarim Basin.
