Abstract

Urbanization is one of the most significant features of current social progress. Using Landsat TM/OLI images from 1995, 2005, and 2018, the land-use change, vegetation coverage, and land surface temperature retrieval of Hefei are studied, and the driving force of Hefei’s expansion is analyzed. The influence of urban expansion and vegetation coverage on the intensity of the urban heat-island effect is discussed. As the city develops, various factors, such as natural conditions, economic growth, demographic changes, and policy decisions, are driving the expansion of construction land in Hefei. The overall performance shows expansion to the southwest of the main urban area, the surface temperature rises as the city expands, and the area of the heat-island effect also increases, showing the trend of multi-center distribution. There is a clear negative correlation between land surface temperature and vegetation coverage. Therefore, increasing the city’s green infrastructure can effectively alleviate the severe heat-island effect.
