摘　　要：应用2000—2011年NCEP/NCAR再分析逐日6 h 1°×1°资料,分析了新疆天山山区对流层不同层次空中水汽输送特征,结果表明:(1)天山山区地面～100 hPa每年平均有11 504.1×108t水汽输入,11 337.0×108t水汽输出,水汽净收支为167.1×108t,其中西、北边界为输入,东、南边界为输出,对流层中层水汽输送量最大,低层次之,高层最小。天山山区水汽总输入量占全新疆水汽输入量的44.1%。(2)各季节中夏季水汽输送量最大,春季、秋季相当,冬季最小,各季节西边界、北边界均为水汽输入边界,东边界、南边界均为水汽输出边界。Using the daily NCEP/ NCAR 6 h 1°×1° reanalysis data from 2000 to 2011,the features of water vapor transport at different layers over Tianshan Mountains in Xinjiang are analyzed.The results are as follows.From surface to 100 hPa,11 504.1 ×108 t water vapor（WV） input and 11 337.0 ×108 t WV exported in the Tianshan Mountainous area per year,as a result,annual net WV earning quantity was 167.1 ×108 t.Setting the west and north of the border as input and east and south of the border to export,water vapor transport quantity（WVTQ）at middle layer was the most.total WV input of the Tianshan Mountainous area accounted for 44.1% of the entire Xinjiang WV input.Maximum amount of water vapor transport occurred in summer,less in spring and autumn,least in winter,while the western boundary and the northern border were water vapor input boundary,and the eastern boundary and south boundary were output boundary.The middle tropospheric water vapor input was the most.
