Spatial Distribution Patterns and Influencing Factors of Immovable Revolutionary Relics in Shaanxi Province, China

Taking the list of immovable revolutionary cultural relics published by the cultural relics department as the data source, with the help of ArcGIS spatial visualization method, the spatial distribution characteristics and influencing factors of immovable revolutionary cultural relics are analyzed by using the nearest neighbor index, kernel density estimation, geographic concentration index, imbalance index and geographic detector. The spatial distribution type of immovable revolutionary cultural relics in Shaanxi Province is agglomeration type, and the spatial aggregation presents the characteristics of 'one high and many low' nuclear density; based on the Lorenz curve situation, compared with the uniform distribution state, the distribution of immovable revolutionary cultural relics in the city area shows the characteristics of geographical concentration. The number of distribution shows that Yan'an City and Yulin City in northern Shaanxi are more distributed, Weinan City in Guanzhong and Hanzhong City in southern Shaanxi are the second, and Baoji City and Tongchuan City in Guanzhong are less distributed. The dominant factors of spatial pattern differentiation are slope, elevation, GDP, the number of national traditional villages, and the number of museums/memorials, among which the interaction between elevation and the number of national traditional villages is the strongest.
