 This research examined the impact of land use and land cover changes on the spatial temporal patterns of land surface temperature, LST, in Nanjing, China. It found that the LST of Nanjing has been increasing since 1990, with the mean LST reaching 26.73 degrees Celsius in 2030 under the SSP 585 scenario, integrated scenario of SSP 5 and RCP 5.8. Under this scenario, the LST will continue to increase until 2030. The research also found that the increase in impervious surface area is the main cause of the LST increase in urban heat island, UHI, effect. To mitigate the UHI effect, the researcher suggested that the government should focus on reducing the amount of impervious surfaces in urban areas.
