Abstract: With the speeding up of urbanization, urban population is increasing constantly since the rural people get more chances to work in urban area. There was a huge change of urban structure and topoclimate, so the study on the urban heat island effect has become one of the hottest fields globally. This study focus on  Wuhan city as an example, by integrating five time phase Landsat image data from 2004 to2015, using RS and GIS technologies and the monowindow algorithm with inverting calculation, generating land surface temperature (LST) data and the urban heat island intensity data in recent 10 years, and analyzed the characteristics of the spatiotemporal variation of urban heat island effect in Wuhan city in 11 main districts and the relationship between heat island intensity and the change of landuse type. The results indicated that: (1) the urban heat island intensity decreased continually in the old town, but increased all the time in the new town of Wuhan city after 2007, and the urban heat island area differential between the old and new town was getting smaller, with only 20.74 km2 gaps in 2015. (2) The urban heat island area of Dong Xihu district, Cai Dian district, Jiang Xia district and Hong Shan district increased more dramatically than other jurisdictions in Wuhan city in recent years. The interannual variability of the heat island area in Jiang Xia district was the largest and the peak value was 95.42 km2. (3) The results of fitting relationship between heat island area and landuse type area in Wuhan city from 2004 to 2015 showed that the R2 value between the urban heat island and building land arrived the maximum 0.681 2. The increase of the building land area was an important factor for the heat island area rise in Wuhan city.
