中文摘要	利用1960 -2009年间黑河流域及其周围15个气象站点的逐月气温观测数据,运用多年趋势线法、Mann - Kendall法、小波分析等方法,对黑河流域气候变化进行了研究。结果表明:近50年来黑河流域气温总体呈增加趋势(P值为0.027
英文摘要	Heihe River is located in the arid region of northwestern China. The observed meteorological data collected from 15 weather stations covering the 50 -year period from 1960 to 2009 were analyzed to understand the trend of air - temperature change,cyclic and abrupt in Heihe river basin,by employing linear trend analysis as well as Mann -Kendall rank analysis, wavelet, R/S, and abrupt analysis. The result showed that: on the whole,the annual mean air- temperature in Heihe river basin markedly had a upward trend with the warming rate of 0.28℃/10a (at the a=0.05 significant level p=0.027)during the recent 50 years. The result indica- ted that the temperature of this region increased by 1.4℃ in the last five decades, which rose slowly about 70- 80s temperature in twentieth Century, until temperature rose significantly after nineteen ninties. For the spatial distribution, the average annual temperature changed gradually from west to east showing a warming trend,in which the eastern watershed upstream and downstream temperatures heated up a big margin to the middle and lower reaches of folk music Ejinaqi the most significant; Annual mean air - temperature changed in Heihe river basin fluctuated with a cycle of 10 -15 and a subordinate cycle of 5 years. Particularly, the 13 years oscillation was dominated. The annual mean air temperature in Heihe river basin abrupt change point was in 1987,prior to the point was a cool stage and after it a warm stage emerged. Further analysis of climate warming on agricultural production can provides references the rational use of local resources and the sustained and stable development of agriculture.
