Research has been conducted on the spatial heterogeneity of heritage networks, with a study focusing on Luoyang graded heritage networks using a specific analytical approach. Other related studies have examined heritage corridor construction in various regions of China, including Suzhou and Hubei, as well as the spatial pattern of archaeological sites in Shanxi Province. The use of different analytical methods, such as minimum cumulative resistance models and discrete global grid systems, is also being explored in the context of heritage research.
