Abstract: The spatial-temporal variations of observed temperature based on the 13 stations for 1960-2008 and the 20 stations for 1978-2008 in the Beijing region were analyzed. A rapid decreasing rate of -1.27℃/10a during 1960-1969 , an increasing rate of 0.79℃/10a during 1969-1983 , and a rapid increasing rate of 1.17℃/10a during 1985-1998 are observed by the 13-station temperatures. A slowing-down period from 1998 to 2008 with trends of 0.02℃/10a and -0.05℃/10a are revealed by the 13-station and 20-station observations, respectively. During 1998-2008, warming trend still exists in the urban region. The warming rate in the northern urban region is double of that in the southern part. In the rural area or the stations near a water body or park, decreasing trends are observed during 1998-2008.

Key words: Beijing, warming trend, spatial-temporal variation, slowing-down period
