Abstract:: Based on the comparative analysis of city and suburbs, using data of Xi’an urban heat island effect from 1959 to 2007, the introduction of sudden change analytic method and every year’s urban population of Xi’an, 49 years’ seasonal changing characteristics of heat island effect in Xi’an and their causes were analyzed, which indicated that: Xi’an heat island effect rose up in a form of straight line at 0.322℃/10 a and there were two sudden change years, namely 1980, 1993.The main contribution to the heat island effect is the rise of relatively low temperature. Xi’an heat island effect changes seasonally, the strongest in spring, followed winter and summer, and autumn the weakest. There is a strong linear relationship between the heat island effect and population. The city’s development has an impact on the seasonal changes of heat island effect, the strongest in spring, followed in winter, and summer and autumn the lowest.
