This study aims to explore the sustainability performance of urbanization and its environment in the scope of megalopolises in China, based on the proposed assessment system of urban sustainability. That is defined as the ratio of the two dimensions: quality of the built environment and environmental pressure. The quality of the built environment includes urbanization economies, infrastructure development, and urban attraction. With the help of statistical data analysis and geoinformatics methods, the corresponding assessment and spatio-temporal analysis results are obtained using national official statistics. The empirical results of four Chinese major megalopolises (Yangtze River Delta, Pearl River Delta, Shandong Peninsula and JingJinJi) show that the urban sustainability model is applicable to conveniently combine various analytical methods to help multiple parties reach a common consensus for guiding a reasonable, efficient and sustainable urbanization process.北九州市立大
