中文摘要：
根据汾河流域上、中、下游典型市区54年（1954—2007年）气温观测资料，运用气候统计分析法、累积距平和信噪比法对汾河流域气温变化时空特征进行了分析。结果表明：汾河流域54年来气候呈现暖干化趋势，年均气温整体呈现上升趋势，总降水量整体呈现下降趋势；汾河流域气温变化呈上升趋势，10a平均增幅为0．24℃；汾河流域进入21世纪初期气温上升幅度减小，且上、中、下游气温悬殊差距缩小；经气温变化的突变分析得出54年来汾河流域气温不存在突变年，1960年、1996年分别是汾河上游、汾河中、下游小的气温转折年，1993年是汾河流域大的气温转折年。
英文摘要：
Based on the air temperature data of the upper, middle and lower reaches of Fenhe river basin in 54 years （in 1954 -2007a）, and using climatic statistics analysis method,accumulative annomaly and signal/noise ratio method, the temporal - spatial change characteristics of air temperature over the region were analyzed . The results indicated： （1） The climate was warming and drying in Fenhe river basin in 54 years. Average annual temperature was on the rise as a whole , and total precipitation showed a downward trend. （2） Annual temperature was rising , and 10 years average of temperature increased about 0.24℃. （3） The rise of warming was reducing in the early 21th century, and the temperature gap of upper, middle, and lower reaches was reduced. （4） The temperature mutation Fenhe river basin did not exist, 1960 and 1996 were the small temperature turning points, 1993 was a big turning point in Fenhe river basin in Shanxi province.
