Abstract: The change of temperature and the characteristics of the urban heat island effect were analyzed with climatology and statistic methods based on annual meteorological data from 1961 to 2000 at 17 stations in Shijiazhuang area. The results indicate that there was an increasing trend of temperature in Shijiazhuang in the 40 years, and 1981 is a break of the change of temperature; its urban heat island effect was obvious with average intensity of 0.59 ℃. The intensity was increasing at averagely 0.006 6 ℃ per years, and after 1980s’ it increased more remarkably. The average intensity of 1981—2000 increased by 0.10 ℃ compared with the counterpart of 1961—1980. The enhancement of urban heat island effect of Shijiazhuang is strongly relevant to the acreage of developed urban area.
