The humidity ratio of each location was calculated according to data of temperature and relative humidity after correcting them to be synchronous. The results show that the humidity ratio in south suburb is higher than that in urban centre and north suburb in winter in Xian City. Urban dry island intensity is about 0.3 g/kg(dry air) in daytime and 0.4 -0.5 g/kg(dry air) in nighttime, influenced by urban heat island, the relative humidity increases from urban centre to suburbs gradually,the differences of relative humidity between urban centre and suburb are about 10％RH and 20％RH in daytime and nighttime, respectively.
