Heritage Corridor Construction of the Grassland Silk Road in Inner Mongolia Based on MCR Model

Taking the cultural heritage along the Grassland Silk Road in Inner Mongolia as the research object, this paper used ArcGIS tools to locate and quantitatively analyze the spatial distribution characteristics of cultural heritage, and used the minimum cumulative resistance MCR model to carry out the single factor overlay analytic hierarchy process, so as to carry out the multi-objective suitability analysis, provide optimization basis for the comprehensive evaluation of the spatial location, construction scope and pattern of the Grassland Silk Road heritage corridor in Inner Mongolia, and generate the heritage corridor construction model. According to the research findings: 1) the cultural heritage along the Grassland Silk Road is concentrated in Hohhot-Baotou-Erdos of midwest and Chifeng of east of Inner Mongolia, and the spatial distribution pattern and trend are distributed along the southwest to northeast axis; 2) central area is with the highest suitability in site selection of heritage corridors. The highly suitable areas showed a point-like distribution with heritage points as the core, the medium-high suitable areas showed a "linear group + multi-point" distribution pattern, and the suitable areas showed a "ribbon" distribution in the central Inner Mongolia, staggered distributed with the medium and high suitable area; 3) through optimizing and selecting, we formed: 1 level-1 corridor main line (Alxa Right Banner-Tongliao section), 2 level-2 heritage corridor branch lines (Bayan Nur-Tongliao section, Ejin Banner-Hohhot section), and 1 level-3 heritage corridor branch line. The compound cultural heritage development network is with the main line as the core and assisted by branch lines.
