Abstract: Using ArcGIS spatial analysis method, 283 national and provincial intangible cultural heritages in 68 counties （cities, districts） of Sichuan-Shaanxi old revolutionary base area were studied. The results showed that the intangible cultural heritage resources in Sichuan-Shaanxi old revolutionary base area were rich, and the spatial distribution of different types of projects was obviously different. The number of traditional skills was the largest, the number of folk art and folk literature was small, and entertainment, acrobatics and traditional sports were the scarcest; the spatial agglomeration of intangible cultural heritage in Sichuan-Shaanxi old revolutionary base area showed a five-level trend, and the local or cross-regional agglomeration distribution characteristics in the administrative area were obvious; the intangible cultural heritage of Sichuan-Shaanxi old revolutionary base area was mainly distributed in the area of 212~686 m above sea level, and the number of intangible cultural heritage of the same type decreased obviously with the increase of sea level; the distribution of intangible cultural heritage and rivers in Sichuan-Shaanxi old revolutionary base area had a good spatial coupling degree, showing strong hydrophilicity. In the 14~20 km river buffer zone, there was a small contrarian growth process, and then a cliff-like decrease until the distribution number was 0; modern transportation was not the influencing factor of intangible cultural heritage, but the highly developed modern transportation network provided strong support for the inheritance, protection and tourism development of intangible cultural heritage.
