利用1955-2009年西藏那曲气象站（NQ站）和2001-2009年BJ野外气象站（BJ站）的观测资料，对NQ站和BJ站气温、风速的变化特征进行了对比分析。结果表明，BJ站的年平均温度和最低温度均低于NQ站，年平均风速反之；两站（NQ站-BJ站）温度差的增长率依次为最低温度（0．117℃·a^-1）〉年平均温度（0．034℃·a^-1）〉最高温度（-0．014℃·a^-1），年平均风速为0．076m·S^-1·a^-1；以青藏铁路正式通车的2006年为界，20012005年和2006-2009年分别为人类活动影响较弱期和较强期。人类活动影响较强期与较弱期相比，两站温度差异增加的幅度依次为最低温度（0．512℃）〉年平均温度（0．152℃）〉最高温度（-0．025℃），年平均风速为-0．198m·S^-1。“,”Using the meteorological data obtained at NQ station in 1955-2009 and BJ station in 2001-2009, the differences of temperature and wind speed at the two stations were analyzed. The results showed that both the annual average temperature and the minimum temperature at BJ station were lower than that at NQ station while the annual average wind speed at BJ station was higher than that at NQ sta- tion from 2001 to 2009. The increasing rate of the temperature difference between NQ station and BJ sta- tion performed as the minimum temperature （0. 117℃·a-1）〉the annual average temperature （0. 034℃·a-1）〉the maximum temperature （-0. 014℃·a-1） in order, and the rate of annual average wind speed was 0. 076 m·s-1·a-1. According to the strength of anthrogenic activities and the Tibetan Plateau Railway was built in 2006, the period of 2001-2009 were divided into two periods, one was the period of 2001-2005 as the weak period, another was in 2006-2009 as the strong period. Comparing with temper- ature in the weak period, the differences of the minimum temperature between the two stations in the peri- od of strong human activitie had the marked increase with 0. 512℃. The temperature differences showed the minimum temperature （0. 512℃）〉the annual average temperature （0. 152 ℃） the maximum tem- perature （-0. 025 ℃） in order, and the difference of annual average wind speed was -0. 198 m·s-1.
