Spatial distribution of urban expansion across different suitability levels in China from 1990-2020. The map reveals significant regional variations in urban development patterns: blue areas indicate high suitability expansion, green shows relatively high suitability, orange represents moderate suitability, while purple and red indicate relatively low and low suitability expansion respectively. Eastern coastal regions demonstrate concentrated high-suitability urban development, particularly around Beijing, the Yangtze River Delta, and the Pearl River Delta. In contrast, western regions show scattered low-suitability expansion, highlighting the uneven spatial adaptation characteristics of China's urban development over the past three decades.
