Abstract:
The interannual variation of the urban heat island effect in Jinan is analyzed based on the observation data from 1964 to 2006, and it is found out that the annual average temperature in Jinan shows an obvious rising trend since 1951 By using the hourtohour temperature data of 2007 to 2008 from the local automatic meteorological station, in combination with GIS data, the spatial and temporal distribution of urban heat island effect in Jinan is obtained. The results show that the urban heat island intensity in Jinan is the greatest around the Quancheng Square, the municipal government, with a ringshaped distribution in all seasons. The heat island intensity is the strongest in winter, then autumn and spring, the weakest in summer. The urban heat island intensity exhibits the diurnal variation pattern of greater at night and less in daytime. The urban heat island intensity shows regular change with a period of a day and has a feature of rapid formation and rapid disappearance.
