The study on the spatial distribution pattern and driving factors of immovable cultural relics resources can reveal the law of their historical development, present the process of regional civilization and cultural development, and provide a reasonable basis for their protection and sustainable utilization. With the help of GIS spatial analysis functions geographic detectors are used, taking the immovable cultural relics as the research object, discusses their spatial pattern and its influencing factors. The results show that: The urban spatial distribution of immovable cultural relics is agglomerated and "dual-core and multi-center". Its spatial differentiation is influenced by geographical and environmental factors such as altitude, slope, aspect, distance from water resources, administrative center, military center and traffic road, there are obvious differences in the single factor detection, the slope is the strongest explanation of natural geographical environment factors, and the setting and change of administrative center in human geographical environment factors also play a leading role in the spatial differentiation structure. The interaction between the factors has obvious synergistic enhancement effect, indicating that the spatial pattern differentiation is significantly affected by the comprehensive influence of multiple factors.
