In order to understand the distribution pattern of the resources of arbuscular mycorrhizal (AM) fungi in arid zones in northwestern China, we investigated AM fungal diversity in five vegetation types: desert, grassland, forest, meadow, and oasis farmland. Forty AM fungal species belonging to six genera were identified from the rhizospheres of 60 plant species. Of these fungi, 35 were identified to species and five were identified to genus. Glomus claroideum was the dominant species throughout the sampling area, but the occurrence and distribution pattern of AM fungi in the five vegetation types were quite different. Entrophospora was only observed in desert while Paraglomus was found in oasis farmland and desert, Archaeospora existed in grassland, desert and oasis farmland, and Scutellospora existed in meadow, forest and grassland. The biodiversity index in oasis farmland and meadow were higher than other vegetation types, indicating soil moisture may be the most important factor affecting the distribution of AM fungi in arid zones.
