摘要:
基于阿勒泰地区7个气象站1961—2012年逐日气象资料，采用Penman-Monteith模型计算了逐日参考作物蒸散量，运用Mann-Kendall非参数检验法、小波分析法，并结合ArcGIS软件对作物参考蒸散量的时空变化特征进行了研究。结果表明：阿勒泰年和春季作物参考蒸散量呈增加趋势，而夏季、秋季和冬季作物参考蒸散量呈减少趋势。年和夏季的作物参考蒸散量分别在1994年、1992年发生突变，而春季、秋季和冬季的作物参考蒸散量则没有发生突变。年和四季的作物参考蒸散量都存在27 a的周期。空间分布上，年、春季、夏季和秋季的平均作物参考蒸散量呈自阿勒泰市南部和福海县西北部向东部、南部和西部逐渐递减的变化趋势。而冬季作物潜在蒸散量大致呈现自西向东逐渐递减。变化趋势上，春季潜在蒸散量在空间上都呈增加趋势，而年、夏季、秋季和冬季的潜在蒸散量在阿勒泰的东部呈增加趋势，在西部则呈减少趋势。
Abstract:
The values of reference crop evapotranspiration were calculated using the Penman-Monteith model based on the daily meteorological data observed from 7 meteorological stations in Altay region of Northern Xinjiang Uygur Autonomous Region during the period from 1961 to 2012. The annual and seasonal values of reference crop evapotranspiration were analyzed using the Mann-Kendall nonparametric method, wavelet analysis and spatial analysis tools of ArcGIS. The results are as follows. The annual and spring values of reference crop evapotranspiration presented significantly increasing trend, whereas the summer, autumn and winter values of reference crop evapotranspiration presented decreasing trend during the past 52 years. The annual and summer values of reference crop evapotranspiration presented abrupt change in 1994 and 1992, respectively. However, the values of reference crop evapotranspiration in spring, autumn and winter have no abruption. Obviously, the annual and four seasonal values of reference crop evapotranspiration have 27-year period. The annual, spring, summer and autumn values of reference crop evapotranspiration were higher in the southern Altay City and northern Fuhai County, followed by eastern and western regions. The spring values of reference crop evapotranspiration all presented increasing trend in Altay region, whereas the annual, summer, autumn and winter values of reference crop evapotranspiration presented increasing trend in eastern region of Altay and decreasing trend in the western region of Altay.
