While traditional tools and linear models offer insights, they fall short in presenting a holistic view of complex urban challenges. System dynamics (SD) models that are often utilized to provide holistic, systematic understanding of a research subject, like the urban system, emerge as valuable tools, but data scarcity and theoretical inadequacy pose challenges. The research reviews relevant papers on recent SD model applications in urban sustainability since 2018, categorizing them based on nine key indicators. Among the reviewed papers, data limitations and model assumptions were identified as ma jor challenges in applying SD models to urban sustainability. This led to exploring the transformative potential of big data analytics, a rare approach in this field as identified by this study, to enhance SD models’ empirical foundation. Integrating big data could provide data-driven calibration, potentially improving predictive accuracy and reducing reliance on simplified assumptions. The paper concludes by advocating for new approaches that reduce assumptions and promote real-time applicable models, contributing to a comprehensive understanding of urban sustainability through the synergy of big data and SD models.展开更多

For the urbanization, more land inside or around the limited cities have been exploited at the expense of greenery to build buildings as well as infrastructure to satisfy the according demands caused by urbanization. But human beings can never live without greenery, and more citizens mean more needs on greenery. In view of this, the importance of greenery has been increasingly recognized by urban planners and policy makers. This essay aimed to explore the role that greenery plays in urban planning in modern Britain and provided the theoretical basis for better utilization of greenery in the future urban planning.展开更多
