Abstract This paper, based on Landsat TM/TIRS between 1987 and 2015, deduced the surface temperature of the main city, conducted the normalized treatment of the land surface temperature, analyzed the evolution mechanism of the thermal environment in Wuhan City and discussed the characteristics of its diffusion model. The results show that the urban thermal environment has changed greatly in Wuhan City during the past 30 years. With the expansion of urban construction land, the diffusion pattern of the thermal environment pattern has evolved from the initial point-distribution to the stripe shape and zonal-distribution. The formation and evolution mechanism of the thermal environment in Wuhan City is closely related to the natural factors, such as solar radiation, atmospheric circulation and underlying surface properties, as well as the human factors, including the urban construction and development stage, planning policy, and so on.
