Abstract: Distribution of VAM fungus communities in different artificial forests consisted of 7 Eucalyptus species in Guangdong、Guangxi and Fujian Provinces were reported in the paper.26 species of VAM fungi isolated from the rhizosphere of Eucalyptus trees belong to 4 genera: Glomus Acaulospora, Sclerocytis and Scutellospora. Among them 17 species (including unidentified species) in Glomus, 4 in Sclerocytis, 3 in Acaulospora and l in Scutellospora take respectively the ratios of 65.4%, 15.4%, 11.5% and 3.8% of the total VAM isolated.VAM fungi were examined in all soil samples in the survey. Glomus formosanum, Glomus geosporum, Acaulospora myriocarpa, Glomus verdiforme and Glomus sp.No.“23” were generally prevalent species in rhizospere of different Eucalyptus trees. Glomus formosanum and Glomus geosporum are impotant resources of VAM fungi in the Eucalyptus field in Guangdong and Guangxi respectively. Glomus mosseae which mainly distributed in alkaline soil in the north of China were also discovered in the weekly alkaline or alkaline soil in southern China.
