To explore the type and diversity of arbuscular mycorrhizal fungi( AMF) of P. multij lorum in Dongshan, Guiyang, and to provide a theoretical evidence for the dominant species on the artificial cultivation of application. By using acid fuchsin staining and wet-screening method, the root colonization rate of the roots of P. multijlorum were measured, and identified by their morphological characteristics and diversity analysis. The result showed that the root colonization rate of P. multijlorum was 7. 5%. 55 species of four genera and one species not identifyied were isolated from the rhizospheres. including 31 species of Glomus, 22 species of Acaulospora. one species of Scutellospora, and one species of Diversispora. G. liquidambaris, G. badium and A. sporocarpia were the dominant species. The AMF resources were rich in P. multij lorum, Glomus and Acaulospora were of strong adaptability and wide distribution in Dongshan area.
