Computational urbanism and the spatial evolution of Dashilar, Beijing, China

Abstract

Beijing’s urban development follows a cyclical pattern, reflecting its evolution from ancient dynasties to modern times and highlighting the challenges of balancing historic preservation with contemporary urban growth. The Qianmen Dashilar area in Beijing, China, rooted in the traditional hutong system, exemplifies these challenges and serves as a focal point for exploring strategies to harmonize heritage conservation with dynamic urban transformation. This article examines the evolution of the Dashilar area during the urbanization process, focusing on the transformation of its urban structures and courtyard houses. It aims to address the long-standing challenges of preservation and regeneration faced during the area’s urban transformation. To tackle these issues, the article proposes the use of computational methods to establish dynamic urban models based on modulated urban programs and crowd flow dynamics. By developing three computational urban prototypes - cell aggregation, mixed blocks, and node control - through site analysis and data collection, this study re-establishes the connection between the urban grid and urban programs while revitalizing courtyard spaces. These methodologies aim to balance the preservation of Dashilar’s traditional urban fabric with the diverse living demands arising from urban growth. In doing so, the article advocates for a multi-dimensional approach to safeguarding the area’s cultural and historical heritage while supporting its future urban regeneration and evolution.
