Understanding urban expansion's spatial and temporal evolution is crucial for sustainable development. Previous research primarily focuses on two-dimensional perspectives, overlooking vertical This study investigates three-dimensional expansion in Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (YRD), Pearl (PRD) from 1998 to 2018 using Local Climate Zone (LCZ) data, standard deviation ellipse, compactness indicators, landscape ecology techniques. Findings reveal that BTH showed minimal variation direction. YRD predominantly expanded northwest. PRD eastward. Scattered patches with declining density characterize areas. Open lowrise buildings dominate the YRD, while transitioned compact open buildings. The increase corresponds rising complexity fragmentation. highrise buildings, though dominant, show a gradual decrease. offers comprehensive insights into dynamics of expansion, aiding developing more habitable efficient cities.
