Evaluation of urban expansion and its impact on surface temperature in Beijing, China

Urban expansion in Beijing between 2004 and 2009, particularly around the central axis, led to a significant increase in built-up areas by approximately 139.19 km² (4% of the study area) and altered land surface temperature (LST) patterns. High-temperature zones were initially concentrated south of the central axis, extending to the fifth ring road in 2004, but this distribution was mitigated by 2009. The study found a strong negative correlation between LST and NDVI for both years, with LST changes accounting for about 40% of NDVI changes. This suggests that urbanization not only increases built-up areas but also significantly impacts thermal environments, potentially influencing local climate dynamics.
