We made the near-surface luminance temperature through the sixth band of Landsat TM /ETM + sensors from 1988 to 2010. We analyze the space structure characteristic and the change of area percent,the result showed that the position of high heat island was stable,but the large low and sub-low area change to the middle,sub-high and high temperature areas. The heat island extended from north-east to south-west,and the areas of heat island was enlarge in 20 years. The reason for these may be the change of the city's underlaying surface resulting from the urbanization,so how to improve the composition of the underlaying surface,is desiderate for relieving the Handan's heat island effect.
