中文摘要	基于1961-2013年塔里木河流域26个气象站逐日观测资料及阿克苏河流域与和田河流域水文站逐日径流资料,采用基于互补相关理论的平流-干旱(advection-aridity,AA)模型,计算并分析塔里木河流域实际蒸散发(ETa)时空变化特征,研究ETa与下垫面供水及气象要素的关系,探讨塔里木河流域ETa变化的可能原因.结果表明:(1)ETa与潜在蒸散发(ETp)呈现良好的互补关系,AA模型能够用来估算塔里木河流域的ETa.(2)塔里木河流域多年平均ETa为252.0 mm·a~(-1),1961-2013年呈现先增后减(以1996年为转折)、总体增加(11.1 mm·(10a)~(-1))的趋势.ETa在1990s最高,1980s次之,随后为2000s、1960s、1970s.各季节ETa大小为:夏季>春季>秋季>冬季.(3)塔里木河流域ETa在源区较高,流域中部和东南部较低;流域大部分地区ETa呈显著的增加趋势.(4)1961-2013年,流域ETa的增加最主要由下垫面供水条件(径流和降水)以及实际水汽压的增加引起;1997年后ETa的减少是由径流和实际水汽压的减少所致.
英文摘要	The complementary relationship between actual evapotranspiration ( ETa) and potential evapotranspiration( ETp) was verified,of which ETa was estimated by water balance and ETp was calculated by Penman firstly,in the Tarim River basin ( TRB) in the arid inland region of Northwest China. The advection-aridity model based on complementary relationship was calibrated by the ETa estimated by water balance and is proved that it can be applied to the TRB. The research results show that average ETa in the basin is about 252. 0 mm· a~(-1) . An overall upward trend of ETa had been significant from 1961 to 2013,with a rate of 11. 1 mm ·( 10a)~(-1) . However,it has decreased since 1996. The strongest ETa occurred in summer ( 155. 2 mm·a~(-1) ) , followed by spring ( 58. 4 mm·a~(- 1 ) ,autumn ( 33. 7 mm·a~(-1) ) and winter ( 4. 8 mm·a~(-1) ) . ETa had increased significantly since the 1980s till the end of the 1990s,and then it had decreased,and the ETa in the 1990s was higher than that in other decades,followed by that in the 1980s,2000s,1960s and 1970s. The spatial distributions of annual and seasonal ETa were mostly consistent,with generally higher ETa in the sources of TRB,while lower ETa in the lower reaches of the river. The increasing ETa was closely related to the increasing water supply ( runoff in mountain edge and precipitation both) ,together with actual vapour pressure increase from 1961 through 2013. The decline of ETa after 1996 has been caused by decreasing both of runoff in mountain edge and actual vapour pressure.
