Abstract: The military fortresses along the Ming Great Wall are the integral part of the Ming Great Wall's military defense system. How to protect and utilize the great amount of military fortresses along the Ming Great Wall is a key issue to be solved urgently. This paper is guided by the concept of heritage corridor, with 80 traditional settlements along the Inner Great Wall in Shanxi Province as the research object, based on adaptability analysis, taking the minimal cumulative resistance (MCR) model as the path. The GIS method is used for multi-factor spatial superposition, and constructs heritage corridors which take the traditional settlements as protection objects. In the adaptability analysis, the heritage corridor resistance factors include four aspects: regional elevation, terrain slope, road traffic and river system. By grading the relevant resistance factors and assigning coefficients with weights to the impact factors, the comprehensive suitability evaluation map of the traditional settlements along the Inner Great Wall in Shanxi Province can be obtained. In general, the areas with higher suitability for traditional settlements are mainly concentrated near traffic trunk lines, rivers and basins. Then the areas with lower suitability are mainly mountains and hills. Based on the above suitability evaluation results, using the cost path tool of ArcGIS 10.5 to generate multiple shortest paths to simulate the potential heritage corridor space of traditional settlements along the Inner Great Wall in Shanxi Province. In addition, the heritage corridor protection strategies are proposed from the regional perspective, in order to promote the improvement of the living environment along the Ming Great Wall, and to provide scientific methods and paths for the protection and utilization of traditional settlements in the region.
