中文摘要	利用2005 - 2010年塔克拉玛干沙漠腹地气象资料计算了极端干旱区塔克拉玛干沙漠腹地参考作物蒸散量(ET_0)，并与气象站蒸发皿蒸发量(E_p)进行了对比分析及影响因素的灰色关联度排序。结果表明:极端干旱区ET0最大值出现于7月，最小值则出现在1月;Ep最大值分别出现在6月，最小值出现在12月。灰色关联分析表明，在年时间尺度上与ET0关系最为紧密的气象因子是U_(mean)，其次是T_(max)，而影响E_p气象因子最为紧密的气象因子是T_(max)，其次是U_(mean);在春、夏、秋、冬四个季节尺度上夏季对影响ET_0和E_p的气象因子差异最大。ET_0与E_p在春、秋、冬三个季节都成极显著关系，而在夏季呈显著线性关系，因此在不同时间尺度上二者可以进行互相替换。
英文摘要	Pan evaporation (E_p ) and crop evapotranspiration (ET_0 ), as a measurement of soil - plantation - atmosphere transfer system models, which influence the application of models and the precision of prediction, has traditionally been used for water use and water consumption of plant. The changing trend of pan evaporation and crop evapotranspiration are also attracting attention from the hydrological community worldwide due to its indicative meaning in hydrological cycles. In this article, compared the two results from Penman - Monteith formula and pan evaporation based on daily meteorological data from 2005 - 2010 of Tazhong weather station in hinderland of Taklimakan Desert, grey relational analysis was conducted characters of the pan evaporation, crop evapotranspiration and different effects of meteorological factors, and the correlations between ET_0 and E_p were analyzed. The results indicate that there is the same trend in both crop evapotranspiration and pan evaporation of the years. The maximum of the ET_0 appears in July and the minimum appears in January. However, the maximum of the E_p appears in June and the minimum appears in December. Meanwhile, the figures of reference crop evapotranspiroaion vary from 0. 30 to 0. 46. The grey relational analysis showed that there is a close correlation between ET_0 and U_(mean) , just ahead of T_(max) . On the contrary, the pan evaporation is a strongly relation with U_(mean) , then U_(mean). The scale of different seasons of ET_0 and E_p has different affected of meteorological factors and the maximum meteorological factors of otherness appear the summer. The correlative analysis showed that there is a very significant correlation between ET_0 and Ep with the spring, the autumn and the winter. Nevertheless, the relationships of ET_0 and E_p are significant correlation in summer. The results of research are provided some scientific insights on the water use, water consumption of the shelterbelts along the Tarim Desert Highway as well as the management of groundwater. In addition, these results can also shed a light on the sustainability of shelterbelts along the Tarim Desert Highway.
