【Objective】Distribution of arbuscular mycorrhizas （AM） fungi in rhizospheric soils of Beihai and Qinzhou sugarcane planting areas in Southeast Guangxi was investigated in order to provide fundamental references for mycorrhizal fungi resource conservation， and the selection and utilization of elite bacterial strains. 【Method】The soil samples（5-20 cm）of rhizosphere were collected from Beihai and Qinzhou sugarcane fields， AM fungal spores were separated using wetting sieve decantation and sucrose centrifugation method， and identified on the basis of morphological characteristics of the species. 【Result】 Six spore species of AM fungi including 2 of Glomus， 3 of Acaulospora and 1 of Scutellospora were identified in the soil samples. 【Conclusion】 Among arbuscular mycorrhizas population in experimental sugarcane rhizospheric soils of Southeast Guangxi， Acaulospora and Glomus are in the ascendant. The strain A.sp1 presents the maximum in both of two sugarcane planting areas， and the special species of AM in Qinzhou and Beihai is A.sp2 and S. gregaria， respectively.
