The impact of urban growth on the heat island alsohas been studied by statistic analyzing economic and social development of Beijing. Three urban stations andseven suburb stations were chosen to investigate diurnal and long-term variation of the urban heat island. Theconclusion can be drawn as following: ( 1) The UHI intensity and the total population logarithm of Beijing arecreditable correlated, and the long-term correlative coefficient reaches to 0176. ( 2) The urban expansion( construction cover) is very obvious in Beijing, and the scope of theUHI is spreading simultaneously. ( 3) Theincreasing trend of UHI intensity is also found in Beijing. It shows that the UHI has been intensified at a ratioof 0122 e per 10 years. In 1999, the nightly UHI intensity reached the maximum, 1113 e . ( 4) Similar toprevious studies for other cities, the maximum UHI intensity is more frequently observed in the nighttime than inthe daytime, and it is generally more than 015 e . ( 5)The seasonal trend of UHI intensity is similar for differenttimes ( 02: 00, 08: 00, 14: 00 and 20: 00) of a day. The maximum intensity appears at the nighttime at 02: 00and the minimum at noon at 14: 00.Keywords Beijing urbanization, Urban heat island ( UHI) , Long-term trend, Diurnal variation4912006M1 o CHINESE JOURNAL OF GEOPHYSICSVol. 49, No. 1Jan. , 2006V1 4_M1Table1 Informationof 10 selectedstations1 2 3 4 5 6 7 8 9 10ggguuuuuuu_ZF!lvh(bE) 116153 116130 116189 117110 116170 116139 116105 116125 116120 116107(bN) 39198 39185 40142 40115 39190 40109 39192 40124 39192 39155Z(m) 4611 5512 7010 7611 2811 3815 4011 4718 7419 92171 V50MWgv?Z,g?a8La#g?3vM.g6?Zg9FPuf, 2000Mg500 km2,200 km2,40 km2,9750 km2.g?Zg/?3vM,iOtZYg.BZgYMYgH,6BZgVM/VoM.Ngga?rab9Pgu,7uRu.,TgHv4.V 1；4EZEu,ig1983 1985M1z(1u214 e , 8zK014 e 116 eW.
