ABSTRACT: With the rapid development of urbanization, a series of urban ecological problems have emerged, such as the urban heat island (UHI) effect. This paper uses Wuhan city as a study area, applying a total of 11 remote sensing images from Landsat to examine 27-year (1989 to 2015) land surface temperature (LST) in summer and winter, and analyzes the UHI patterns qualitatively and quantitatively. We explored the relationships between LST values and natural factors (percentage of water body and artificial surface) and socioeconomic factors (population, GDP and energy consumption). The results indicated that the UHI was more serious in summer than in winter. For long time scales, the structure of UHI within the third ring road experienced a compact and decentralized evolution with a turning point in 2010. In terms of the influencing factors, both natural and socioeconomic factors were highly correlated with LST, in which the natural factors were more direct. The correlations between socioeconomic factors and LST were enhanced first and then decreased. Taken together, these findings reveal the evolution characteristics of UHI and its influence factors, which are helpful for improving the planning and management of city ecological environments.
