Heritage Identification and Preservation Framework for Industrial Settlements from a HUL Perspective: A Case Study of Tongguan Ancient Town

At present, industrial heritage preservation in China often focuses on individual industrial buildings, lacking a holistic consideration of industrial settlements (e.g., industrial cities, towns, and villages). This study draws upon the Historic Urban Landscape (HUL) approach to construct a research framework that applies to industrial settlements, considering both integrity and layering. Taking the case of Tongguan Ancient Town—a typical industrial settlement—this study uses the integrated approach of historical materials acquisition, oral interview, and field investigation to review the interactive evolution of industry and space across three historical periods. It identifies a comprehensive set of heritage elements within the Tongguan industrial settlement and proposes a preservation framework for its industrial heritage. The key findings are threefold: industrial settlement heritage possesses characteristics of integrity and layering; the HUL approach can be effectively applied to industrial settlement studies; and the protection of industrial settlements is a crucial step toward establishing a complete system for the inheritance and preservation of China’s urban and rural historical and cultural heritage.
