Abstract: The Great Wall of the Ming Dynasty is an important linear cultural heritage in China. A large number of military fortresses are distributed along the Ming Great Wall in northern Shaanxi. Constructing a cultural heritage corridor is conducive to promoting the overall conservation and sustainable development of these fortress settlements. This paper takes 45 fortress settlements as research objects. Based on the basic geographic information database of the study area, we first use the Minimum Cumulative Resistance Model (MCR) and the spatial analysis module of ArcGIS 10.8 platform to perform weighted superposition operations on six types of resistance surfaces: elevation, slope, Normalized Difference Vegetation Index (NDVI), land use type, distance from rivers, and distance from roads, generating a comprehensive resistance surface analysis map. Second, using the Cost Distance tool for calculation, we conduct a multi-level classification evaluation of the spatial suitability of fortress settlement source activities. The evaluation results divide activity suitability between sources (fortress settlements) into four gradients: high suitability area, medium suitability area, low suitability area, and unsuitable area. Finally, based on the above suitability evaluation results, multiple shortest paths are generated, forming a cultural heritage corridor along the Ming Great Wall in northern Shaanxi.
