中文摘要	利用黄河源头玛多、玛沁两个气象站1961~2010年50年逐月平均气温和降水量资料,采用Mann-Kendall等检验方法分析年和四季的气候特征及气候变化趋势,并对气候突变进行了检验。结果表明:近50年来黄河源头表现出气温升高、降水量呈微弱增加、地表蒸发量增大的变化趋势,并且在90年代后期变化趋势更加明显,这种气候变化趋势加速了黄河源头草地退化和沙化。
英文摘要	Statistical data of monthly average temperature and precipitation from 2 weather stations in Maduo and Maqin from 1961~2010 were tested by Mann-Kendall test to analyze the annual and seasonal climate characteristics and the climatic change tendency.The results indicated that in the nearly 50years,there was a tendency of temperature ascension,slight precipitation increase and transpiration rate increases in the upper reaches of the Yellow River,and the tendency was more obvious in late 1990s.This kind of climatic change tendency has accelerated the climate warm desication background degeneration and the desertification of the upper reach of the Yellow River.
