This article takes the digital scene of parks as its starting point and examines the architectural model of the digital system within parks, presenting a novel research perspective. This paper reviews the fundamental types, construction status, and future trends of park digitalization scenarios. It proposes a system architecture model that balances the digital transformation of park systems with the personalized development of parks, considering key factors such as the context of Park City, industry policy directions, and development constraints. The study noted that China’s park digitalization efforts have achieved remarkable progress. However, significant room for improvement remains in construction and maintenance costs, standardized construction, data mining, and usage. The digital development of international parks offers advanced concepts that can inform technology applications, top-level design, and construction philosophy, which should align with China’s national conditions. By reviewing and refining the practical experiences of domestic park digital system architecture models, using Shanghai as an example, the current park digital system reveals three typical models: “Isolated”, “Centralized,” and “Multiple.” Each model has its applicable contexts and should not be simplistically praised or criticized based solely on technological advancement. To address the challenges of development constraints, this article proposes a “one core and multiple modes” architecture model comprising a unified general core, selectable development modes, and replicable functional modules. The aim is to promote system integration, reduce overall costs, enhance personalized functions, and elevate the overall digitalization level of the park system, providing robust support for Park City management and services.
