Abstract:

Based on the monthly mean，maximum and minimum air temperatures from 1971 to 2010 in Guyuan and Liupanshan moun-
tain weather stations and GDP and population data in Guyuan，the effect of urbanization on the variation trend of the air temperatures
was analyzed with the Liupanshan mountain stations as the background field． The results show that the mean，maximum and minimum
air temperatures of Liupanshan mountain and Guyuan had a significant upward trend in the past 40 years． The temperature in the 1980s
was higher slightly than that in the 1970s，and the magnitude of the warming in the 2000s was the highest in the past 40 years． In-
crease in the minimum air temperature was more dominant than that in the maximum air temperatures，the air temperature in winter was
more outstanding than that in summer，and the temperature in Guyuan was more significant than that in Liupanshan mountain． With the
temperature variation characteristics of Guyuan，the maximum and minimum temperature in Liupanshan mountain existed an obvious a-
symmetrical variation，but the asymmetry of Guyuan was bigger than that of Liupanshan mountain，especially during the winter and
summer，the asymmetry was more prominent． In addition，the influence of urbanization had accelerated the increase of the annual and
seasonal mean temperature，the minimum temperatures and the maximum temperature in summer and winter in Guyuan，and it may
play a leading role in the formation of asymmetrical temperature variation and depressing the maximum temperature in summer going
up．
