Abstract: On the basis of collecting 357 items of intangible cultural heritage data in Qujing, the geographical concentration index value and location entropy are calculated, and the nuclear density distribution pattern of Qujing intangible cultural heritage is made by using arcgis10.4 nuclear density spatial analysis tool to explore the spatial distribution characteristics of Qujing intangible cultural heritage and analyze its influencing factors. The results show that the spatial distribution of Qujing intangible cultural heritage is relatively concentrated, and the spatial distribution pattern of "one core and two areas" is formed; Luoping County is the polar core center; Huize County, Qilin District and Malong district are the dense area centers, and the nuclear density concentrated areas are mainly concentrated in the south, and sparse in the north. The factors of nature, economy, population, transportation and government management have certain influence on the formation and distribution of intangible cultural heritage.
