Abstract：

As populations in Chinese urban regions become increasingly concentrated, adopting high-density morphological strategies has emerged as a critical path to addressing urban challenges. This paper focuses on density as a quantitative concept and form as a spatial concept. Employing a futurist “wavefront” methodology, it examines the four iterative density paradigms throughout the evolution of modern urban forms, thereby revealing the dialectical, multi-dimensional progression toward complexity. By considering digital twin technology as the intelligent engine for building future highdensityhuman habitats, this paper elucidates the quantitative and formal categories of density and form, as well as their coupling mechanisms. It proposes the conceptual model of a “Form-Digital Twin” (FDT). Based on this model, the research analyzes the four-dimensional digital linkages of density, human-scale, space, and performance, along with three mechanism modules of sampling, evaluation, and optimization. These findings hold promising implications for the management and design of future high-density urban forms.As populations in Chinese urban regions become increasingly concentrated, adopting high-density morphological strategies has emerged as a critical path to addressing urban challenges.
