From 12 August to 21 November in 1991, 65 soil specimens were collected from nineteen leguminous plant roots throughout nine locations of four provinces. They were sieved to collect and identify the arbuscular mycorrhizal spores (four genera, 21 spades). The species of Glomus were most commonly (47.6% of all observations) found, but the species of Gigrtspora (about 4.8% of all observations) occurred infrequently or rarefy rather than the species of the other genera. The most common arbuscular mycorrhizal spades at nine locations were Acaulospora laevis and Glomus laminated spores cf. macrocarpus var. macrocarpus. All of nineteen legume plant spades collected were found to be associated with the arbuscular mycorrhizal fungi. Cassia mimosoides var. nomame and Kummerowia striata in legume plants had the great frequency of arbuscular mycorrhizal fungi associated with their roots. The number of isolated spores were ranged from 03 to 10.0 spores per 10g of soil. The spades diversity of arbuscular mycorrhizal spores at the disturbed areas were calculated to be bigger than those in the natural vegetation areas.
