摘要:
准确评估参考作物蒸散量的变化规律对新疆农业生产及水资源合理利用具有重要作用，采用Penman-Monteith公式以及55个气象站的逐日气象资料，计算了新疆1961—2013年参考作物蒸散量并分析其时空变化特征，运用多元回归分析法对影响参考作物蒸散量变化的主导气象因素进行了定量分析。结果表明：新疆ET0总体呈下降趋势，年际变化率为-1.01 mm/a。在20世纪80年代之前ET0偏高，90年代减少到最大，2000年以来又逐渐增大。从季节来看，夏季、秋季的ET0与年ET0的减小趋势一致，春季冬季ET0的减少趋势不明显。在不同年代际时间尺度，新疆全年及季节ET0的年际变化在空间上存在一定的分异。风速是全年及夏、秋季ET0变化的主导因素，而温度是春季及冬季新疆区域蒸发量变化的主导因素。
Abstract:
Study on characteristics of the spatial and temporal variation of reference crop evapotranspiration (ET0) is a very important for hydrology and agriculture in Xinjiang Uygur Autonomous Region. Based on the meteorological data of 55 stations in Xinjiang during the period from 1961 to 2013, the annual and seasonal reference crop evapotranspiration was calculated using the Penman-Monteith model and the tempo-spatial change characteristics was analyzed. The multiple regression analysis was used to quantitatively analyse the dominant factor affecting the reference crop evapotranspiration. The results indicated that annual ET0 presented the decreasing tendency, the tendency rate of annual ET0 was -1.01 mm/a. ET0 was higher before 1980s than after 1980s, and experienced the process from the decrease during 1990s, while it showed an increasing tendency since 2000. The decreasing tendency of ET0 in summer and autumn was quite similar to that of annual ET0, the decreasing tendency of ET0 was not obvious in spring and winter. There was the marked geographical difference in ET0 in different seasons. The wind speed and temperature were the dominant factors influencing ET0. The wind speed is main reason for the annual, summer and autumn variations of the ET0, temperature plays the major part in spring and winter variations of the ET0.
