With the rapid development of urbanization in China, the changes of urban subsurface properties caused by the expansion of construction land have increasingly serious negative impacts on the urban thermal environment. This paper aims to investigate the correlation between built-up area morphology and urban thermal environment, and takes the six districts of Xi′an City as the research object, extracts the boundaries of the built-up area from 2002-2021 based on Landsat remote sensing images and derives the quantitative parameters of its morphology, and at the same time, calculates the indicators of the corresponding year′s surface temperature through the inversion of the surface temperature, and then conducts the correlation analysis between the two. The results show that the maximum value of surface temperature has a highly significant correlation with the area and perimeter of the built-up area, and the mathematical model is established by curve fitting for the two groups of data and the specific functional equations are derived, which can be used as a reference for the optimal design of the urban thermal environment.
