As a distinguished representative of red culture, the remains of the Third-Front Construction hold signifi cant research and practical value. In contrast to industrial heritage situated within urban core areas, the remains of the Third-Front Construction— primarily dispersed across towns and villages—are fragmented in distribution, pose challenges for quantifi cation, and suff er from substantial deterioration. Such remains are generally ensnared in a dual predicament: high operational and maintenance costs and the severance of community memory, resulting in isolated heritage enclaves that necessitate systematic consolidation. To address these issues, this study fi rst proposes a multi-scale analytical framework for the remains of the Third-Front Construction. Taking 15 Third-Front Construction remains in Anshun City, Guizhou Province as specifi c research objects, it then summarizes the spatial pattern characteristics of the remains at three scales: corridor-cluster, town-village, and unit-element. The findings reveal that, with the gradual dissolution of factory boundaries, the remains of the Third-Front Construction are transitioning from complete closure to conditional openness. Originally fragmented brownfi eld patches have been integrated into the regional ecological and rural landscape pattern. Topographic elements within the heritage are prominent, with mountainous landforms reshaping the spatial structure, gradually forming a hybrid landscape intertwined with Third-Front landscapes and vernacular landscapes. Moreover, due to historical legacies and functional replacement, the remains exhibit complex nested characteristics of spatial property rights. Against the background of urban-rural integration and rural revitalization, the conclusions of this study provide insights for establishing protection and activation mechanisms for the remains of the Third-Front Construction.
