Abstract  The evolution characteristics of monthly mean temperature are analysed by using the monthly mean temperature data from 1951 to 1990 in Lanzhou.The main characteristics are as follows:the annual mean temperature was higher in the early fifties,then temperature dropped slowly until the sixties and the temperature rose fluctuantly in the late sixties.The temperature was the positive departure from 1985 to 1990.In recent 40 years,temperature evolution process was a warm-cold-warm processes,the temperature rpse obviously in winter and its amplitude was rather small in summer.Comparison between the temperature in the eighties and one in the fifties,the annual mean temperature rose 0.5℃ in the eighties,it rose 2.4℃ and 0.7℃ in winter and autumn,respectively and it dropped 0.3℃ and 0.2℃ in summer and spring,respectively.There are better persistence and the periodicity for the temperature variation in Lanzhou.Its variation is affected by the large-scale circulation,sunspot,urban devolopment and urban heat island effect.
Key words:  Air temperature      Climatological characteristics      Urban heat island effect
