摘　　要：rhizospheric soil samples were collected from 45 wild plants distributed in Shandong Province during 1995～1997. More than forty species of AM fungi were isolated, and the effects of some soil factors on AM fungi were also investigated. It was proved that soil conditions were important factors to the colonization, growth, and distribution of AM fungi. Spore numbers were highest in brown earth, and lowest in alkali saline soil. Glomus occurred in all types of soil. The occurrence frequency of Gigaspora and Scutellospora was much higher in brown earth. The distribution of AM fungi was also affected by soil pH. Glomus occurred in soil with a wide pH range. The greater of soil alkalinity, the more Glomus were found, while the greater of soil acidity, the more Acaulospora were isolated. Scutellospora occurred mostly in soil with pH of 6\^0～7\^0, and Gigaspora distributed mainly in acid soil.rhizospheric soil samples were collected from 45 wild plants distributed in Shandong Province during 1995～1997.
