Using the meteorological data obtained at NQ stationin1955-2009 and BJ station in 2001-2009, thedifferences of temperature and wind speed at the two stations were analyzed. The results showed that both the annual average temperature and the minimumtemperature 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 station from 2001 to 2009. The increasing rate of the temperature difference between NQ station and BJ station 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 in2006, the period of 2001-2009 weredivided into two periods, one was the period of 2001-2005 as the weak period, another wasin 2006-2009 as the strong period. Comparing with temperature in the weak period, the differences of the minimumtemperature between the two stations in the period 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 temperature (-0.025 ℃) in order, and the difference of annual average wind speed was -0.198 m·s^-1.
